A. Hello mom Babies in this age tend to almost double their birth weight and then they triple it by the age of one year so you have to take care that the baby is taking your feed as well and as good healthy high calorie solids as well if the baby was a preterm baby then they would have they grow on a slow pace as compared to a full term baby as well
