Parents Serious Opinion on Preschool Hours?

[Jendayi E]

Well, I have to work part time to support my daughter and I.

She is 3.4 and has been at home with me, but she will start preschool next month. This is a preschool/daycare and I have the option of half day or full day. I will only work 20 hours a week so I have these options;

M-W (8am-3pm) or M-F (8am-11am)

Should I put her in for 3 full days or 5 half days? I will work 20 hours either way, but I don't know what I should choose.
