Lots of meals in the freezer that you can just whip out when you get home.

Childcare - if it is near work, then you get to spend extra time each day travelling and you can be there quickly if little one gets sick. But it might be difficult with the extra travelling (ie public transport I imagine would be harder than if you're in the car).

As for how DD copes with being at CC full time, we are lucky in that DH is a teacher, so she gets a 2 week break at the end of each term. Also, my mum tries to come and visit in the middle of each term and give her a couple of days off. Without fail, she gets a cold in the last week of term which I think is just her little body getting tired.
