Willow, Jack isn't quite 3 yet but has been close to dropping his day sleep for a while. He will go for spells of 2 or 3 weeks where he might only have one or two day sleeps the whole time. Luckily he always seems to get over the phase and go back to sleeping well most but not all days. He is asleep atm but didn't sleep yesterday so it is a bit hit and miss. But luckily he is sleeping most of the time atm.

Friends of ours have a DD who dropped her day sleep just shy of 3 1/2. But other kids that age still sleep at day care so I think it depends on the child.

I suggest that you keep persisting for a little while in case it is a phase that she gets past. I am sure you are really dreading her dropping the sleep, especially now while your DS is not sleeping well. GL with it, I hope she goes back to sleeping. If not, I guess there are always DVDs!!
