little one's and school

My 3 year old daughter started school on Monday of this week.  For those of you that are about to embark on the same traveled road, here is a piece of advice, prepare them weeks in advance and get them exited.  Perhaps even go as far as showing them the school several times & even driving by from occasion.  Report- my little one did great; she even took her mandatory nap from 1pm to 3pm( which never before would she agree to taking naps).  Now my 2 yr. old daughter  wants to stay & play but I thinks that's pushing it.
