If you do not feel that its a good experience keep her home.Trust your instincts.Now looking back on my own childrearing years I realize how fast it goes.I did send my youngest to preschool.I ran a very successful program at home.Like you I thought he needed more socialization.I was wrong,it was kind of a pain.I was unable to go to some of the parent programs and pick up was a pain.He remembers none of it and did not seem any more adjusted than his 3 siblings. I think the red flag for you is there.You noticed the sleeping in corner incident,the cupcake issue.I would talk to the teachers especially if you have an older child at the school.I would keep my 3 yr old at home.Its for the morning only lunch and nap.Seems like you pick up early.Maybe just withdraw for this year and reaccess for next .year. I think you have valid reason to be concerned.
