Most schools have a pre-registration day during the summer for the kids and parents to come and get a packet of info and some school type materials. It is usually something like "Breakfast with Mom" and last maybe 2 hours. It is a meet and greet for you, the child, and the other children and parents. If this is done, go to that, you will more than likely stay with her during that time. If that is not done in your area, make arangements with the school and the teacher she will have if possible to visit the school and walk her through the halls, room, bathroom, lunch facilities if it is all day and play areas. Talk it up, all the other posted advice about books, etc. is quite good. They are right, it will probably be harder on you than her. Think about her clothing also, easy to pull up for bathroom time, also easy wash (they should paint a lot) and definitely comfortable. Some schools if it is connected to a public school require uniforms, find out before you purchase. Look at their schedule and visit. There should be group time, quiet time, music time, play time, outside time. And it should be fun, this is introduction to fun learning. And yes, some do cry all day. Some even go home with mom early but that is a bad habit to begin and even harder.You did not state your reason for sending her now, and it may be time for her to go. BUT actually, she does not HAVE to go according to academic requirements, and yes I feel the darts coming my way for that statement.States vary on their requirements. Where I live children are not required to attend any schooling until they enter 1st grade. Preschool and kindergarten do have their place, I taught both. BUT this is your decision and you may have reason to send her at this age and she does need to interact with others. Since she is an active preschooler this may be the best place for her. It is your decision. And as others mentioned there are 1/2 day preschools, Moms day out, etc. available in some areas. As her mother, I know you will find the best answer for you and your daughter. God Bless.
