hi gayathri patil, i just wanted to tell you that your child indeed appears to be healthy and its weight appropriate for its age.. it is a common notion among parents and elders in family that child is not putting on weight or the food is insufficient or digestion is poor and so on.. a minimal of 6-8 times urine output in a day, and a fair amount of play time, and weight gain checked during your immunization visits to your pediatrician.. these should be sufficient clues to tell the child is growing well.. a baby doubles its birth weight by 4 months and triples it by 1 yr.. it is due to the fact that natural rate of growth itself starts to slow as child begins to grow.. so as of now according to information you have given the child seems to be appropriate for its age.. hence no medications are required.. just continue to breast feed till the child is 2 years and give him nutritious home made poridge and other food that is age appropriate.. that should do..
