When does a baby start to laugh/giggle?
Usually after around the 12 weeks mark. Even then you may only get one every now and then. It can be like getting blood out of a stone sometimes until they get the hang of it. Get the video camera out as there is nothing like a first laugh.
Anywhere from 1 month - 7/8 months. It all depends on the baby.
My son first started laughing at 2 months old.
my baby started laughing real good at aroudn 4 mths
Whenever they want to, I guess.
