SInce he was quite a young baby, DS has been distressed by people laughing loudly (mild titters don't seem to both him so much). He's 2.11 now and I hand't thought about this in ages, but both yesterday and today he's been in absolutely howling sobbing hysterics because a) my friend laughed when DS tipped the watering can over himself and b) everyone laughed at someone dropping a box of beads at playgroup this morning.
DO other kids do this? Is it a phase he'll grow out of?
