All 3 kids will be going to traditional daycare center this summer, The Goddard School. It's not a bargain, but the benefits definitely are there, so I am at peace with decision. Little Mae will probably start in April, and my KGer will have to go back in before and after Y care until school is out, then it will be his last year to return to Goddard as he will be too old next year!
I do have to pick up an extra day of work outside the home, on Saturdays to fund it, but that's life with 3! But I will be home with children on Fridays and DH and the children on Sundays. I will also continue teaching at the university, which is very forgiving and flexible, so I can make it to parties, field trips, etc. and be more available for sick days majority of the time.
thanks to everyone who served as my sounding board over the past year, a lot of time and research went into this decision!
