My DS is 4 and has always been a bit needy and whiny. These last few months though have honestly been the worst!!! Moans and cries over anything and everything. Doesn’t listen, expects all the nice things even when you explained about his behaviour. Even nursery where he is usually so well behaved have said he’s not listening. Is there some kind of developmental thing around this age?? 4yrs 4mths? He sleeps 7-7 every night, doesn’t nap. Eats well but has recently had a blood test which has shown up as low Ferratin and plasma, not sure if any of that makes a difference……… Help!!!
