Frequently Asked Questions
What milestones should my baby reach by 3 months?
By 3 months, babies typically should be able to lift their head while lying on their stomach, push down on their legs when their feet are placed on a hard surface, and begin to smile at people. If you have concerns, consult your pediatrician.
How can I support my baby's development at this age?
Engage with your baby through talking, singing, and playing. Tummy time is crucial for muscle development, and exposing your baby to various sounds and sights can stimulate their sensory development.
Is it normal if my baby doesn't coo at 3 months?
While most babies begin to coo by 3 months, variations exist. If your baby isn’t cooing or making sounds, it’s advisable to discuss this with your pediatrician to rule out any concerns.
What should I do if my baby seems overly fussy?
Fussiness can be common at this age, but if it seems excessive, consider factors like hunger, tiredness, or the need for comfort. If you’re worried, contact your healthcare provider.
When should my baby start seeing a pediatrician?
Regular check-ups should begin shortly after birth, with the first major visit around 1 month and continued visits at 2 months, 4 months, and so on. This ensures proper monitoring of growth and development.
