12 Month Old Baby
BabyWhat to expect at 12 months — your baby's first birthday.
Welcome to Month 12. Your baby is officially turning one year old. Over the past year, they have learned how to smile, laugh, sit, crawl, communicate, eat, and explore. They have gone from a completely dependent newborn to an active little person with a growing personality and a strong desire for independence. This month is a celebration of everything your family has accomplished together.

Frequently asked questions
Should my child be walking?
Some children walk before their first birthday, while many healthy children begin walking several months later. There is a wide range of normal.
How many words should my child say?
Some children say several words by their first birthday, while others communicate mainly through gestures and sounds. Both can be completely normal.
Is it normal to be emotional about the first birthday?
Absolutely. Many parents feel proud, nostalgic, and amazed by how quickly the first year has passed.
Is my baby a toddler now?
Many people consider the first birthday the beginning of toddlerhood, although development happens gradually rather than overnight.
Looking ahead
The next stage is toddlerhood. During the coming year, your child may learn to walk, run, climb, talk, solve problems, express big emotions, and develop an even stronger sense of independence. The first year may be ending, but a whole new adventure is just beginning.
