Frequently Asked Questions
What are the main physical milestones for babies in their first 3 months?
In the first three months, babies typically gain head control while lying on their stomachs and may start to roll over. By the end of this period, they can usually hold their head up at a 45-degree angle.
When should my baby start to respond to sounds?
Most babies start to respond to sounds by around 2 months. They may turn their head towards familiar voices or sounds, indicating their developing hearing and social skills.
How can I support my baby's development during this time?
Engage in regular tummy time, provide varied sensory experiences, and respond to your baby's coos and gurgles to encourage communication and social interaction.
Is it normal for my baby to sleep a lot in the first few months?
Yes, it is completely normal for newborns to sleep 14 to 17 hours a day. Sleep patterns will vary, and it's essential to create a safe sleep environment to reduce the risk of SIDS.
How can I tell if my baby is developing normally?
