ds2 (14 months) threw up all over me on Thurs afternoon when I picked him up from nursery, next day had seriously gross watery nappies so put it down to bug, since then off food, stinky nappies (runny but not that bad), all 4 molars coming through and being sick at least once a day - could it be teething? books say teething doesn't cause runny nappies or sickness tho so am I ignoring signs that he's struggling with something? he's drinking water ok but not alot and sleeping loads, usually has 2 naps, one 45min one 1.5hr and then sleeps 7-6.30 but at mo having 3 naps, and sleeping longer at night usually in bed by 6.30pm
