The Fourth Trimester

How to Support Your Body in the First Six Weeks After Birth

The weeks after birth are often described as the fourth trimester, a time of intense physical, hormonal, and emotional change. While much attention is placed on pregnancy and birth itself, how you care for your body in the first six weeks after delivery has a major impact on recovery, long-term comfort, and confidence in movement. Across Tunbridge Wells, Kent, and Sussex, we regularly support women who feel unsure what they should (and shouldn’t) be doing postnatally. Many are told simply to “rest”, while others feel pressure to return to exercise or normal routines too quickly. The fourth trimester isn’t about bouncing back. It’s about repair, recalibration, and gradual re-integration.

What’s Happening in the Body After Birth

In the first six weeks post-birth, your body is:

• Healing soft tissues and connective structures
• Adapting to changes in pelvic floor and abdominal load
• Rebalancing hormones
• Recovering from labour, assisted delivery, or surgery
• Adjusting posture in response to feeding, carrying, and disrupted sleep

Even if birth felt straightforward, pregnancy and delivery place significant physical demands on the body. Recovery is an active process that benefits from guidance and support.

What’s Normal in the First Six Weeks Postnatal

Common and Normal Experiences

Many women notice:

• Fatigue that feels deeper or more persistent than expected
• Pelvic heaviness or aching
• Lower back, hip, or rib discomfort
• Abdominal weakness or a sense of “disconnect”
• Neck, shoulder, or upper back pain related to feeding
• Emotional ups and downs

These experiences are common and do not mean something has gone wrong.

When Extra Support May Be Helpful

Consider seeking professional guidance if you experience:

• Persistent pelvic heaviness or pressure
• Ongoing pelvic, back, rib, or hip pain
• Pain around a C-section or perineal scar
• Difficulty reconnecting with breathing or pelvic floor movement
• Increasing discomfort linked to feeding or carrying your baby

Early postnatal support can often prevent these issues from becoming longer-term problems.

The Priority of the Fourth Trimester: Recovery First

The first six weeks are not about fitness goals. They are about:

• Healing
• Restoring coordination
• Reducing unnecessary strain
• Rebuilding confidence in movement

Trying to rush strength or high-impact exercise too early can delay recovery rather than support it.

Breathing: The Foundation of Postnatal Recovery

Breathing is one of the most important, and often overlooked tools in early postnatal recovery.

Gentle, relaxed breathing supports:

• Nervous system regulation
• Pelvic floor reconnection
• Abdominal wall coordination
• Pain modulation

Early postnatal breathing should feel soft, unforced, and comfortable, allowing the ribs and abdomen to move naturally.

Pelvic Floor Care in the Fourth Trimester

In the early weeks after birth, the pelvic floor benefits from:

• Gentle awareness
• Light, coordinated activation
• Full relaxation between efforts

This is not the stage for strong or repetitive pelvic floor contractions.

Persistent heaviness, pain, or uncertainty around pelvic floor function is a good reason to seek assessment rather than guessing.

Abdominal Recovery and Core Support

After pregnancy, the abdominal wall has adapted significantly. Early recovery focuses on:

• Coordination rather than strength
• Gentle support during everyday movement
• Avoiding aggressive “core” exercises

Activities such as standing up, lifting your baby, and getting in and out of bed provide enough stimulus when supported by good breathing and posture.

Movement in the First Six Weeks Postnatal

Movement is important in the fourth trimester, but it should be intentional and supportive.

Helpful early postnatal movement includes:

• Short, comfortable walks
• Gentle mobility for the spine, hips, and rib cage
• Frequent position changes

Supported posture during feeding and carrying

The aim is to restore movement without adding strain.

Gentle Fourth Trimester Movement Checklist

• Short walks that feel restorative
• Gentle spinal and hip mobility
• Relaxed breathing with rib movement
• Pelvic floor awareness with full relaxation
• Comfortable feeding and carrying positions

Be cautious with:

• High-impact exercise
• Intense abdominal work
• Breath holding during movement
• Ignoring pain, pressure, or scar discomfort

Recovery is not linear, listening to your body matters.

Posture, Feeding, and Postnatal Aches

Feeding and caring for a newborn place new demands on the body.Common postnatal aches and pains are often linked to:

• Prolonged feeding positions
• Holding the baby on one side
• Looking down for long periods
• Sleep deprivation and reduced movement variety

Neck, shoulder, upper-back, rib, and lower-back pain are very common in the fourth trimester and often respond well to gentle osteopathic treatment and posture-specific advice.

C-Section Recovery and Scar Therapy

If you’ve had a caesarean birth, recovery includes not just healing of the incision, but how the scar integrates with surrounding tissues.

Postnatal scar therapy may help:

• Reduce sensitivity or pulling sensations
• Improve abdominal and pelvic movement
• Support posture and confidence in movement

We offer C-section scar therapy, including gentle techniques and Lymphatouch, to support healing, circulation, and tissue mobility once appropriate.

The Role of the Mummy MOT in Postnatal Recovery

A Mummy MOT® appointment is a structured postnatal assessment tailored to your individual needs and includes:

• A detailed case history and discussion about your recovery, lifestyle, and goals.
• A full postural screen to assess alignment and movement patterns.
• A pelvic floor muscle assessment (if required), with guidance on how to correctly contract and relax these muscles.
• An abdominal assessment to check for muscle separation (diastasis recti).
• Screening for bladder, bowel, or sexual function changes.
• Assessment of c-section scar if relevant

Many women benefit from a Mummy MOT around 6–8 weeks postnatally, particularly if they want reassurance, guidance, or a clear recovery plan rather than generic advice.

How the Fourth Trimester Sets the Foundation for the Future

The first six weeks after birth play an important role in long-term pelvic floor health, how confidently and comfortably you return to exercise and strength training, your postural comfort, and your overall confidence in movement.Taking time to recover well now often makes later stages of recovery smoother and more resilient.

Final Thought

The fourth trimester is not about rushing forward.

It’s about allowing your body the time it needs, supporting the healing process, responding early to aches and discomfort, and slowly restoring confidence in how your body moves and feels.

With the right guidance, the first six weeks after birth can feel supported, informed, and empowering, rather than overwhelming or uncertain.
