The best thing that any worrier can do is take a deep breath. (I do this a lot).

Are you sure you can't take on at lest one more kid. I live in a 1000 ft 2 bedroom apartment and although I don't open my daycare until Oct. I know that I can fit a total of 5 kids in it. (I borrowed my friends kids one day. We did crafts and had nap/quite time, basically I did daycare for the day to see how it would work) it was a little tight but doable.

If you PM me I will send you my web address and you can see photos of my daycare area.

If you can get at least one more kid, maybe you wouldn't need to have a 2nd job.

I know for myself it takes me about 2 or 3 months to get fully comfortable in a new job. The first few weeks are always the hardest and I always wonder what have I gotten myself into.
