what should be the weight of 5 months 22 days old baby boy?

A. 6.4 to 9.7 kg is the average weight range for this age group. But it also depends on the baby's birth weight. Your baby should be peeing anywhere between six to ten times a day which means the baby is taking feeds properly. If not then make sure the baby is latching and taking feeds well or if ur milk supply is sufficient. Also there should be a gradual weight gain. Keep a check on these factors.
