Postpartum recovery: the complete guide to your 4th trimester

Whether birth took place vaginally or by caesarean, the body goes through a series of intense changes from the very first hours after delivery. These mechanisms are biological, and understanding them better is already a way of navigating them more easily.

The uterus returns to its size

After housing the baby for 9 months, the uterus must return to its original size. This process is called uterine involution and takes around 6 weeks. Afterpains may be felt in the first few days: these are natural contractions, more intense in those who have had several children and during breastfeeding, as the oxytocin released helps the uterus to contract (1).

The hormonal drop

During pregnancy, the body is bathed in a cocktail of oestrogen and progesterone at very high levels. After birth, these hormones drop sharply within the space of a few hours. This drop is one of the main factors behind the intense fatigue, mood swings and baby blues that many mothers experience in the first few days, alongside sleep debt and the adjustment to a new daily life (2).

Lochia: the body's natural cleansing

Lochia are the postpartum discharge that allow the uterus to eliminate residual tissue (mucous membrane, blood, secretions). They generally last 4 to 6 weeks and evolve: bright red and heavy in the first few days, then pinkish, then yellowish or whitish. A return to bright red or a strong odour should prompt a prompt medical consultation (3).

Fatigue and anaemia

Blood loss during childbirth, which can reach 500 ml or more in the case of a caesarean or complications, can cause iron-deficiency anaemia (4). The result: deep fatigue, dizziness, and shortness of breath. On top of that, sleep debt begins to accumulate from the very first nights. This is not a matter of physical fitness or resilience — it is purely physiological.

The Jolly Mama boost: Hydra Mama

Postpartum fatigue is not solely linked to lack of sleep: the body is also depleted of minerals and hydration, particularly during breastfeeding. Hydra Mama is a powder formula enriched with 4 essential electrolytes: magnesium, potassium, sodium and chloride, which helps to remineralise the body and compensate for losses.

There is no universal answer, and that is important to know. Postpartum recovery is a gradual process, measured in months, not weeks.

• Day 1 → Day 7: afterpains, heavy lochia, milk coming in, hormonal drop, baby blues possible. The body is in immediate recovery mode.
• Weeks 2 to 6: the uterus returns to its normal size, tissues heal (perineum or caesarean scar), and hormones gradually stabilise.
• Months 2 to 3: pelvic floor rehabilitation begins and energy slowly returns. But pain, fatigue, and emotions are still very much present.
• Months 6 to 12: for many women, it is only at this stage that they begin to feel like themselves again — and that is completely normal (5).

Key takeaway: the postnatal check-up at 6–8 weeks is just a first step, not a finish line.

Social pressure — and sometimes family pressure — pushes many new mothers to "get back on top of things" too quickly. Here are the most common pitfalls.

Returning to exercise too soon

Returning to jogging or squats at day 15 is risky. The pelvic floor is weakened, and ligaments remain relaxed under the effect of relaxin for several months. High-impact exercises increase the risk of pelvic floor disorders (incontinence, organ prolapse) by nearly 5 times compared to low-impact activities (6). Resuming exercise too intensely can also compromise the healing of a tear or contribute to abdominal diastasis. This is why returning to running is generally recommended from 3 months postpartum, and not from the 6-week check-up (7).

Neglecting rest

Rest is a healing tool. Chronic sleep deprivation affects healing, mood, and immunity, and can impact milk production. Accepting help and delegating is not an admission of failure: it is a recovery strategy.

Ignoring warning signs

Intense pain around the scar, very heavy or foul-smelling lochia, fever, a red and swollen leg, chest pain, persistent intrusive thoughts: these symptoms warrant immediate medical attention (8).

Skipping meals or not drinking enough

Insufficient nutrition slows healing, amplifies fatigue, and worsens deficiencies. When breastfeeding, caloric needs increase by around 500 kcal per day (9).

The perineum after a vaginal birth

Tearing, episiotomy, or simply the pressure experienced during delivery: the perineum needs gentleness and time. Sitz baths with lukewarm water, gentle hygiene (without harsh antiseptics) and, if needed, prescribed pain relief can help. Prolonged baths and pushing efforts should be avoided. In terms of posture: a firm surface is preferable for sitting (a donut-shaped cushion can help), and alternating between sitting and lying down supports recovery. (8)

The caesarean scar

Healing takes around 6 weeks. The area should be protected from friction, and heavy lifting avoided. Once the scar is well closed (generally around 6 to 8 weeks), scar massage with a suitable oil can help prevent adhesion and improve the appearance of the skin.

Afterpains (post-birth contractions)

These post-birth uterine contractions are more intense from the second child onwards and often intensify during breastfeeding. They generally subside within 3 to 5 days. An antispasmodic or paracetamol may be considered on medical advice.

Moving is beneficial, but how and when make all the difference.

From day 1–3: breathing

Diaphragmatic breathing is the first tool available. Lying down, a deep inhale allows the belly to rise, then a slow exhale draws the navel back towards the spine. This simple exercise stimulates circulation, supports the recovery of the internal organs, and gradually reactivates the pelvic floor.

Weeks 1 to 6: gentle activation

• Transverse abdominal: on the exhale, gently draw the lower abdomen inward. Hold for 5 seconds, repeat 10 times. No pain or pressure on the perineum should be felt.
• Kegel exercises: progressive contraction and relaxation of the pelvic floor, as soon as comfort allows.
• Walking: start with 10 to 15 minutes per day at a moderate pace. This is the only cardio recommended before pelvic floor rehabilitation.

Important: before resuming any more demanding activity (Pilates, yoga, swimming, cycling), clearance from a midwife or doctor is required, ideally after completing full pelvic floor rehabilitation (7).

After pelvic floor rehabilitation

Once the pelvic floor has been rehabilitated (typically between 6 and 10 sessions), a gradual return to activity becomes possible: postnatal Pilates, swimming, yoga. Running is generally not recommended before a minimum of 3 months.

The postpartum period is emotionally intense. Tears, anxiety, and the feeling of being overwhelmed are not signs of poor mothering — they reflect one of the most profound transitions a human being can go through.

Baby blues: normal, but not to be dismissed

Between days 3 and 5 postpartum, around 50 to 80% of women experience baby blues: unexplained tears, irritability, a sense of emptiness or inadequacy. This is largely linked to the hormonal drop that follows birth. It rarely lasts more than 15 days and generally resolves on its own with rest, support, and kindness (10).

Postpartum depression: when to seek help

When symptoms persist beyond 2 weeks — deep and lasting sadness, inability to care for yourself or your baby, overwhelming anxiety, intrusive thoughts, a complete absence of pleasure — this is no longer baby blues. Postpartum depression affects around 10 to 20% of mothers and requires professional support (11).

Postpartum depression is a recognised medical condition, unrelated to the quality of love felt for the child. It responds well to treatment. A GP, midwife, or psychologist specialising in perinatal mental health are the right people to turn to. In France, consultations may be covered under the "Mon soutien psy" pathway (12).

Taking care of yourself every day

• Accepting help without guilt — delivered meals, an imperfect house — all of this is entirely legitimate.
• Keeping social connections alive, even gently: a message, a coffee with a friend.
• Putting words to what you feel — with your partner, a close friend, or a healthcare professional.
• Joining a community of parents (online or in person): the feeling of not being alone is invaluable.
• When breastfeeding, paying attention to your own hydration and nutrition is also an essential form of self-care.
