Yes my dd went to preschool. She didnt really care for it but at that point of time I wasnt given much option by my family members as to whether or not she went. Things are different now and my dh and I make the decisions as to what we feel is best for our child. If we ever have another child we will probably opt not to send them to preschool. I think its a great thing if the child is willing to go but for some kids its just not a good idea.
That is awesome that your daughter loves it. Children grow up so fast, its just unbelievable. Good luck to her in her schooling.
