my baby just completed 3 months .. looks and smiles at us... also makes any sounds... coos in response to us. but the other times hell look here and there.. wenevr i call him out and speak to him , he wil alwes look here and there, sometimes looks at me n starts conversation. is this normal? when wil baby look at me when u start talking to him? other tyms he concentrates on us n smiles but only when he sees us.. if i talk to him he can't look at me always. will look here and there n be in his play. pls answer if this is normal? n also let me knw when they respond spontaneously to our talks by directly looking at us everytime.
