5.30am poo - why?

[fishie]

ds (3.5) has woken at 5.30am for the past three mornings demanding a parent to assist with a poo. he is then up for the day. he is not usually so regular in his habits! any suggestions?

no changes in diet but it is second week of nursery.

maybe anxious that he really doen't want to need to poo at Nursery? I think DS2 went through similar early waking when he started nursery. Now he waits until 30 seconds before we need to leave the house!!

My DS2 always seems to poo around 6am, but he is only 8 months. Does annoy me though as am sure he would sleep longer otherwise.
