I thought this was a motorbike forum not MumsNet Kids are complex creatures. we are lucky with ours, shes two and a half and very easy going. she doesnt have "meltdowns" like many of the kids in our NCT group seem to have. But kids are all different, and i dont think you can start assuming they have mental issues just because they cry at night - its more likely hunger, or too much sugar in the crappy kids food everyone seems to feed children... But there seems to be a link with nursery. All the parents in our NCT group reported that as soon as their kids started going to nursery they turned into little horrors. kind of makes sense really, they go from one-to-one care with mum, to being in a room full of kids competing for the nursery workers attention. My child doesnt go to nursery, she goes to a montessori pre-school for two mornings per week. in our view she's too young to be away from parents any longer than that. Also, you need to wear them out. I see so many two/three/four year olds being pushed about in buggies!! WHY?? they have legs, let them walk, why push them about?? how are they ever going to get worn out if they are not allowed to even walk, and if they are not worn out they will not sleep!! buggies are evil. Then we have beeping plastic toys, ipads,TV's etc etc and all the other electronic junk parents are pushing their kids to "play" with... none of it is good for the developing brain and it teaches them nothing. I'll stop there i think, but i could rant for ages on the subject.. lol
