DS is in bed by 6.30 every night. Most days he still has a 2 hr sleep at lunch time. This weekend we are going to a big family do which means we'll be staying in a hotel and there will be lots of eating out & late nights. I've never done this with DS and am not really sure how he'll cope. Any tips? Also if they go to bed late do they tend to sleep in longer or will he prob wake at the usual time?
