My DS is nearly 11 months and went to nursery at 7 1/2 months.
We have to get him up at 6.20 ao he has a bottle at home and then Breakfast at nursery. He doesn't seem to mind, and I now follow the same routine at weekends. They do seem to feed them a lot at nursery though. He has a snack (toast) at 9ish and then lunch at 12.30. I have asked them not to feed his tea until later than the other babies (4.30) as we don't have time when we get in before he falls asleep. He does have fingerfood at 3.30 though as it seems cruel to make him watch the others eat.
He has a morning sleep and a lunch sleep, if a bit later than he would normally 'cos he is sooo nosey and there is lots going on.
In fact, lately he has decided not to have as much sleep at all, even though he is put in the cot, but he doesn't seem to suffer for it. Our only problem is we don't get home till 6.15 in the evenings, so it's bath, bottle, cuddles, story then bed pretty quickly.
I think having been a GF baby for so long it doesn't really matter what happens during the day now, he always sleeps well at night and seems to eat just about anyting that's put in front of him.
I have stipulated to the nursry that he is only allowed water to drink and now sugary foods at all, not even jam. So they probably all think I'm nasty
Sorry, bit of along answer, but basically what I'm trying to say is, I'm sure your DS will be fine... it'll be you that'll get stressed! For some things you have to go with the flow. I'm sure you'll work it out.
