For those SAHM who went back to work, did you enroll your LO in daycare before applying or getting hired?

The daycare DS was on a wait list for said he could start now. However I'm just starting to look at jobs. Not sure if I should go ahead and put him in. It always seems like there is a wait list and I don't want to get a job and have no child care for DS. However it is expensive with only income right now!
