spoiled?

or, spoilt? Can a child be spoilt, or just egg custard?

Yes, this discussion has been coming for some time, but it appears that my 4 year old is really now officially spoiled(t). It is very hard to impress her; and she now makes day-to-day things difficult, as she deems it a huge chore to a) take a bath! b) eat a meal! or c) put away her shoes! It is really making life less enjoyable around here. Lately I've been concerned that the 9 month old arrival of her brother has been affecting her badly and I should give her extra tlc - and the net result is that she is ever more demanding. You can't please her. (for long.) What used to be a huge treat - i.e. an ice cream sundae - lasts as long as it takes her to eat it. It depresses me.

Do I need to go backward and stop allowing such things for a while? Maybe I should read the next range of child raising books. I'm not looking for reassurance here - as in, 'it's just a phase', as I have given up that ghost - but if you have any advice I'd gladly hear it.
