I childmind in a 2 bed flat. I have a 4yr old who's at school and look after 2 under 2's. At sleep time, one sleeps in my son's room and the other sleeps in the lounge, both in travel cots. During this time, I'm either tidying the kitchen or having a coffee in my room!!
As for school runs, I also think that it's a bonus that the child is out and about in the fresh air. Maybe I'm lucky and have a pleasant walk to school by the river or via a playground.
I don't have much experience with day nurseries and, until I became one, had no experience of cm's. I used to be a nanny and saw childminding as a step down from nannying. I now know how understated cm's are. Any good CM will be able to demonstrate how good they are!!
What type of food would you expect from a 2 course cooked meal? I provide food, usually lunch and tea. Lunch is light then a cooked tea. I provide at least 3 portions of veg and at least 2 portions of fruit per day. This was also something my ofsted inspecter wanted to see.
Good luck with whatever you decide, you'll know when you've found the right carer/s for you child.
P.S. Have you considered a nannyshare? Not as expensive as a nanny but can be more flexible to meet your needs.
