Over the summer I have off of work, but I am doing some online courses and have a bit of professional development to complete as well. I am trying to decide what to do for childcare for my oldest son who will be 4. The factors I am considering:
1. He has been in daycare since he was 18 months old and LOVES his school. He attends full time from 730-430.
2. He always chooses to go to "school" rather than stay home as he is very social.
3. He does best with consistency.
4. He is attending Pre-K in the fall at the local elementary school.
5. MY DS2 will be registered for 9:00am-4:30pm even though I likely won't send him every day but there isn't an option for part time for the littlest ones. (He needs to continue to hold his spot)

Given all of that, I can't decide if I should register him for a reduced schedule every day or a more full schedule 3 days a week? The options I am considering are:
M-F 9:00-2:30pm
M, W, F 9:00-4:30
ETA: The cost is almost the same
What would you do, if you were me?
