... it was fine. :) The staff were warm and friendly and I felt confident handing her over. She was as good as gold and I almost forgot I'd had her - got engrossed in some work at home and picked her up 15 minutes late. 
Never had ANYWAY look after her until today (she is 6 months) but it was great.
Just wanted to make a positive post for those who are worrying about impending returns to work!
