My daughter was about 1½ when she started daycare. It went really well to begin with then she got upset after a couple of weeks and that went over within a month. They did have a bit of a "schooling in" period where you would be there with her for a couple of days for a few hours, then leave for short periods and after a few days leave her there for a few hours on her own.. then finally a whole day.. it took about 1-2 weeks to get that over with but it was a very nice period for not only her but for me as well I got to see how things ran around there and she got comfortable with the place with mom still around.
It will go well, might be a little upset after the newness of the place wears off and they truly understand that you are leaving but it will pass when they see that they are going to have a good time there with friends.
I think it's great that you could work it out to be able to stay home with her.. and I think it's great that you plan on sending her off to daycare when she is older. It's great socialization.
