My baby is 7 and half months old. he has started taking solids 3 times a day but there is no visible health gain. his birth weight was 2.4 and his current weight is 6.9 is this ok..?

A. Namaste Mom, Babies are expected to almost double their birth weight by age of 4 to 6 months and later triple by age of 1, were in you can give them now 2 to 3 main meals, 1 or 2 times snacks and alter it with your feed,
