I know you!
Even though your baby has been able to recognize you since he was just a few days old, he may now be able to show it. About half of babies this age begin to exhibit an obvious recognition of their parents.
Most likely he'll still smile at strangers, especially when they look him straight in the eye and coo or talk to him. But he's beginning to sort out who's who in his life, and he definitely prefers you, your partner, and a select few over others.
Your baby may quiet down and make eye contact with you, or he may search for you in a room and move his arms in excitement or smile when he finds you. He may even find your scent calming and comforting.
A big spurt is happening in your baby's brain development that coincides with significant behavioral changes. Your baby is more attuned to the outside world and more sensitive to changes in his environment.
The part of the brain that governs hand-eye coordination and allows a baby to recognize objects is developing rapidly now. His hearing, language, and smell have also become more receptive and active. When your baby hears your voice these days, he may even look directly at you and start gurgling or trying to talk back.
Early language development
Research shows that babies whose parents speak to them extensively have significantly higher IQs and bigger vocabularies when they get older than other children, so interaction is especially important right now. Set a solid foundation by exposing your baby to a variety of words.
Talk about your surroundings when you take him for a walk, and point to and identify objects as you roam the grocery store aisles. Your baby can't repeat these words yet, but he's storing all the information in his rapidly developing memory.
If your home is bilingual, your baby will benefit from hearing both languages spoken regularly. Don't worry if some of his verbal skills seem to lag a bit at first. He'll not only catch up later, but he may also excel in his general language skills.
Remember, your baby is an individual
All babies are unique and meet milestones at their own pace. Developmental guidelines simply show what your baby has the potential to accomplish – if not right now, then soon. If your baby was premature, keep in mind that kids born early usually need a bit more time to meet their milestones. If you have any questions at all about your baby's development, ask your healthcare provider.
