Ds2 is 25 months and has been not himself since sun/mon last week, no temp I thought he was probably teething just really grumpy. Saw the hv on weds who put it down to teething/his age. Since thurs he has been sleeping 14/15 hours at night which is 2/3 hours longer than usual. Does this sound like I should be getting him checked by the gp? He stopped daytime naps weeks ago so nothing new there, or does it sound like a growth spurt or something?
