👶 Young baby
Your 3-month-old baby
Finding their hands and their voice
By Emma Whitfield · Pregnancy & Baby Writer
Development at 3 months
By three months many babies push up on their forearms during tummy time, hold their head fairly steadily, and discover their hands — watching, clasping and bringing them to their mouth. Cooing and gurgling "conversations" grow.
Feeding
Milk is still your baby's only food — the NHS recommends waiting until around 6 months before starting solids. Feeding patterns are often more predictable now.
Sleep
Night sleep may consolidate into longer stretches for some babies, though this varies enormously and night waking is still completely normal. A simple, consistent wind-down routine can help.
Play & connection
Play gyms with hanging toys encourage reaching and batting. Sing songs with actions, read simple books, and keep up daily tummy time to build the strength for rolling.
Focus this month
Book any outstanding vaccinations and keep your baby's red book handy for weight and length checks. Consider getting out to a baby group — it helps you as much as the baby.
When to check in
Have a chat with your health visitor if your baby cannot hold their head up at all when supported upright, is not responding to sounds or your voice, or is not yet trying to bring hands together.
