Development at 10 months
Your baby may cruise along furniture, clap and wave. They understand more words than they can say, and enjoy simple games.
What you might notice
- Cruises holding on to furniture
- Waves and claps
- Picks up small pieces of food with finger and thumb
- Understands simple words such as no and bye-bye
- Points at things they want
Feeding
Offer a wide range of family foods, cut into safe, small pieces. Avoid whole nuts, whole grapes and other choking hazards.
Sleep
Two naps a day is usual. Early waking and night waking can be part of normal development. Put your baby down on their back on a firm, flat surface with nothing loose in the cot.
Your checklist this month
- Learn infant first aid, including what to do if your baby chokes.
- Cut round foods such as grapes and cherry tomatoes into quarters.
- Read picture books together every day.
