my baby is 4 months and 23 days old...Last month he had viral diarrhoea due to which his weight decreased. but now he has recovered from and he had also started increasing..but suddenly from last week his weight has decreased from 7 kg to 6.5 kg ..I'm very worried about it..should I consult a paediatrician for it..what may be the reason for this..should I feed him more frequently or my milk is not enough for him
