She really wants her son to stay in the daycare. In our state, Pre-K is run through private daycares and this is one of the best. Priority for the Pre-K is given to kids that attend the daycare, so he has to stay there. They don't have part time care either, you have to pay full time.
That was her only real hesitation which is why we offered to pay for him to continue attending the daycare for next year. It's a pretty expensive daycare, but Pre-K will be free for him the following year.
