4 min read · Around weeks 25–28 of pregnancy
You have reached another milestone.
The third trimester is beginning.
Your baby is larger, movements are easier to recognise and the idea of actually meeting the little person inside your bump may suddenly feel much less distant.
How big is your baby at 7 months pregnant?
By around 28 weeks, an average fetus measures approximately 37.6 cm from head to heel — often compared with the length of an aubergine.
Your baby will continue gaining considerable size and weight over the final trimester.
There is still a lot of growing to do.
Owloo Insight
The third trimester is not simply waiting for birth.
Your baby is still developing, growing and preparing for the enormous transition from life inside the womb to life in the outside world.
Movements may feel much stronger
The fluttering movements from earlier pregnancy may now feel like distinct kicks, stretches, rolls or sudden jerky movements.
You may even see your bump change shape briefly as your baby moves.
Every baby's activity pattern is different.
Rather than comparing your baby with someone else's, begin paying attention to what is usual for yours.
Your baby already has periods of activity and rest
Babies in the womb do not move constantly.
You may notice times when your baby seems especially active and others when things become quieter.
As pregnancy progresses, these patterns may become increasingly familiar.
Your body is entering the final stage too
At around seven months, your growing uterus and the additional weight of pregnancy can bring new symptoms.
You may notice:
- backache;
- indigestion or heartburn;
- leg cramps;
- sleeping difficulties;
- feeling warmer than usual;
- a stronger awareness of your growing bump.
Talk with your healthcare professional about symptoms that worry you or feel unusual for you.
A Good Month to Prepare Slowly
You do not need to prepare everything this week.
Start with the things that matter most: where baby will sleep, safe transport, basic clothing and care essentials. Leave the decorative extras until later.
You are entering the preparation stage
Seven months is a useful time to move from thinking about baby products to deciding what you genuinely need.
A newborn needs surprisingly little.
Start with safety and care essentials. Then think about the everyday experiences you want to create once your baby is awake and ready to look, listen and interact.
