It isn't just the having a boss part to consider. There is the issue of is it financially viable to go or to stay too. By the time you subtract daycare for your own children will you make the same take home pay. It also depends on why you left in the first place. If it was work related issues have those been resolved or would you be walking back into the same problems. Mostly it is a list the pros and cons thing and then on each side circle the three most important ones. Then if the pro list looks more positive then go for it and if the con list looks more logical then you stay put at least for now.

Also be sure you have given the home daycare a chance so you will know if you ever want to go back to it.
