Frequently Asked Questions
What physical milestones should my 3-month-old reach?
By three months, your baby should be able to hold their head up at a 45-degree angle when lying on their stomach. They might also start pushing down on their legs when their feet are on a hard surface.
How can I encourage my baby's development at three months?
Engaging in tummy time, responding to their coos, and providing colorful toys can stimulate your baby's physical and cognitive development. It’s also vital to talk and sing to them regularly.
Is it normal for my 3-month-old to not smile yet?
While many babies start to smile socially around three months, some may take a little longer. If your baby shows little interest in social interaction or seems unresponsive, consult your pediatrician.
When should I be concerned about my baby's development?
If your baby is not meeting several of the developmental milestones at three months, such as holding their head up or engaging with you, it is advisable to discuss your concerns with your pediatrician.
How does tummy time help my baby develop?
Tummy time is essential for building neck and shoulder strength, which helps your baby develop the ability to roll over, sit up, and crawl later on. The AAP recommends starting tummy time as soon as the baby comes home.
