It's normal. My baby is same when he I'd born.

At 2 months old, it is normal for babies to have gained some weight since birth. On average, infants gain around 150-200 grams per week during the first few months. However, every baby is different and growth patterns can vary. It is best to consult with your pediatrician who can assess your baby's overall health and growth trajectory. They will be able to provide personalized guidance based on your baby's specific circumstances.
