Teach them to tie their shoes, and double knot them to avoid having to retie them over and over during the day. Teach your child to blow his nose, wipe it and put the tissues in the trash can. Work with your child on how to sit in a group and listen to a story for 10 to 15 minutes. Teach your child to serve herself and make choices. Send an extra change of clothes for your child to keep at school including socks, underwear, shorts and sweat pants.

Put their names on their clothes. Teach them to play with other children and to share. Teach them to write their name and be able to identify the alphabet letters.
