I think the fact that you are questioning whether you are an adequate caregiver means that you are going to be awesome! You just have to find your routines and get into the flow of things. Congratulations on filling your daycare but are you doing school runs morning and afternoon? That would certainly mess up your day and make it hard to get organized.

It's true the winter months also make it more difficult because of all the bundling and unbundling that isn't necessary the rest of the year. I'm lucky and don't have any school aged children so my schedule is as follows:
7:30-8:30 arrivals
8:30 breakfast because it's the most convenient time for me to serve it
9:00-11:00 outside play most of the year, bad weather days are our crafting/creating/inside play days
11:00 freeplay for the children and I make lunch
11:30 lunch
12:00 naptime (right now because my group is all 2 and under)
2:45-3:00 snacktime
3:30 freeplay and pickups

So I keep really busy in the mornings entertaining a lot with songs, stories, dancing sporadically through the morning since my dckids don't sit still very well for a structured circle time. It's different for everybody and even my schedule changes from year to year except for that 9-11am outside time all summer.

What do children do at parks? PLAY. What do they do in the toyroom? PLAY. When I started out my daycare I was trying to entertain the children constantly and it took a long time to realize I don't have to do that.
