My baby is 15 month old and her weight is 7.8 kg not sure about height but it’s less too can you help to increase height n weight

A. Mam the weight is actually very less so you should give all the family foods plus good proteins in the diet both vegetarian and non-vegetarian whatever you would prefer giving to the child along with that please check with your doctor once if you need to start with any health tonic or supplement for your child
