#asktheexperts mam my baby is underweight from birth and also he was in nicu for 15 days for respiratory disorders. He was 2.3 kg when born. Now his weight at 3 months end is 3.6 kg. His body activities are completely normal but social activities are not as per milestones. He makes a little eye contact only . He don’t smile and babble . And i feel vo thoda apni duniya me he khoya khoya rehta hai. Pls let ke know its normal or should i be worried abt this
