When should daughter go to kinder garten?

MiMei has been catched cold about a week and has returned to normal today.Her mother and I took her go to play by the Big River this afternoon.

I found there are two things should be noticed concerning my daughter.One is when should she go to kinder garten and another is eating by herself beacause she is interesting with eating with little scoop now and we shouldn't hit her passion of eating by herself.
