Crèche.... I am terrified :(

[Junglemum]

don't do it to yourself. Or her. Plenty of time to get fit. I was in exactly the same position when dd2 was about 8 months, I went once and left her at the creche, and never went back. It was horrible. After that I'd only go to the gym if dh could watch the girls.
Do you have anyone to watch her at home for an hour while you go? Any other options????

What about doing a half day at a proper childcare centre - with trained staff - do your gym and maybe other jobs for the morning then pick her up?
