How do babies grow and develop in their first year?

Babies typically have several growth spurts during their first year of life. The timing of these growth spurts can vary, but they often occur at: - 2 to 3 weeks old. - 6 to 8 weeks old. - 3 to 6 months old. - 9 to 12 months old. During a growth spurt, a baby may be extra hungry and want to nurse or take bottles more frequently. They may also be fussy, sleep more or less than usual, and grow quickly in height and weight. Growth spurts usually last a few days to a week and then return to a more normal feeding and sleep pattern. It's important to remember that every baby is different and may not experience growth spurts at exactly the same time or with the same intensity. If you have concerns about your baby's growth or feeding patterns, it's best to talk to your pediatrician for advice and support.
