hi my son is 55 days old now his birth weight is 2.9 kgs now his weight is 5.8 kgs is it normal..?

A. Hello dear parent! Definitely good. It is said to be good if the baby doubles its birth weight by 6 months and triples by one year completion. Continue breastfeeding your baby well on demand. As long as your baby is active and healthy, passing adequate urine 6 to 8 times in a day then nothing to worry. Speak to your doctor for further advice.
