My baby is 2 and a half month old, since few days he wants to be held constantly and feed 'all the time ' and cries when I put him down.

A. Try putting him down onto a play mat, or into a swing or bouncy chair. You can play with him while he's down, or even use a rattle or mirror to entertain him. Give it a few minutes. If your baby's on the verge of crying, pick him up and comfort him.
