By Jove I think we've cracked it!

Hoping I'm not tempting fate here, but me, Mr Messy and Princess Lollipop all got a better night's sleep last night :-) I was able to reach over and comfort Princess Lollipop as soon as she disturbed, so she didn't wake up properly and went straight back to sleep. I'm a little fuzzy on how many times it happened, but it was certainly a LOT easier than having to run to her room and try to get her to sleep. And she stayed in her cot all night too, so me and Mr Messy weren't crushed at the edges of the bed trying to avoid flailing limbs and being tickled by her mass of curls :-) Fingers crossed this solves the sleeping issues we've been battling with since we returned home from Ethiopia!
