my baby will be 2 months on the 21st and still no laughs out louds or giggles...every baby is different tho. He does smile alot tho and tries to talk to me.
Development varies. My daughter didn't laugh unless it was farts until around two months. Maybe even closer to three. She's developmentally ahead now at two, so I think it does just vary. You can always ask your ped what milestones to expect at each visit.
