The Fourth Trimester: What It Is and How Embrace Medical Supports You Through It

The "fourth trimester" is the term commonly used for the first three months after your baby is born, a stretch where your newborn is still adjusting to life outside the womb, and you're adjusting to almost everything else. It's not a medical diagnosis, it's a way of naming a season that's genuinely different from both pregnancy and whatever "normal" looked like before, and naming it seems to help. If the last few weeks have felt disorienting, you're not doing it wrong. This is what it tends to feel like.

According to PANDA (Perinatal Anxiety & Depression Australia), up to 1 in 5 expecting or new mothers, and up to 1 in 10 expecting or new fathers, experience anxiety or depression during pregnancy or in the year after birth. That's a lot of families quietly finding the fourth trimester harder than they expected, which is exactly why having somewhere to go, whether that's a class, a group, or a GP appointment, matters.

What does a Fourth Trimester Class actually cover?

On Saturday 10 October, Alyssa Booth, our doula and babywearing consultant, is running a dedicated Fourth Trimester Class at Embrace Medical. It's built around the practical, physical and emotional realities of the first three months: settling techniques, babywearing basics, what's normal versus what's worth flagging to a GP, and space to ask the questions that don't always fit into a 15-minute appointment.

What else is on for postnatal support this fortnight?

• Inclusive Playgroup — Wednesday 7 October
• Fourth Trimester Class with Alyssa Booth — Saturday 10 October
• Weekly breastfeeding drop-in — Mondays, 10am, no booking required
• Weekly yoga — Thursdays, 5.30pm
• Infant massage —

When is it worth talking to a GP instead of, or alongside, a class or group?

Classes and groups are genuinely useful for the everyday adjustment. They're not a substitute for medical care when something specific is going on. It's worth booking a GP appointment if:

• Feeding is painful, or you're not sure your baby is getting enough
• Sleep deprivation has tipped into something that feels like more than tiredness, for either parent
• You're noticing persistent low mood, anxiety, or intrusive thoughts that don't lift
• Your baby's feeding, weight gain, or development doesn't seem to be tracking the way you expected

If feeding is the sticking point, a feeding support consult gives you dedicated time with both the medical and lactation side covered together. If sleep is what's fraying everyone, a sleep support consult is built for exactly that conversation. And if it's less one specific thing and more the whole picture, a deeper support consult gives you the longer appointment that early parenthood often actually needs.

What if it's not about the baby, it's about how you're coping?

‍That's common, and worth naming directly. Our infant mental health post covers why the emotional connection in these early months matters so much, and our broader perinatal health post covers the full picture from pregnancy through the first year.

Healthcare in the fourth trimester should feel like it's keeping pace with you. If this season is harder than you expected, come along to a class, drop into a group, or book a GP appointment, whichever feels like the right first step.

FAQs

What is the fourth trimester?

It's the commonly used term for the first three months after birth, when your baby is still adjusting to life outside the womb and you're adjusting to life as a new or growing family.

Do I need to book for the Fourth Trimester Class?

Yes, for the class with Alyssa Booth on 10 October. The weekly yoga and breastfeeding drop-in don't require a booking.

How common is it to struggle emotionally in the fourth trimester?

PANDA reports up to 1 in 5 new mothers and up to 1 in 10 new fathers experience perinatal anxiety or depression, so if you're finding it hard, you're genuinely not alone.

What's the difference between a feeding support consult and a deeper support consult?

A feeding support consult focuses specifically on breastfeeding or feeding difficulties. A deeper support consult is a longer appointment for when things feel harder more broadly, sleep, mood, adjustment, rather than one isolated issue.
