Find out what the school mascot and colors are.. She will be wearing these colors for the years she is at that school.. This way you can find hair accessories, socks, Maybe a picture frame for her class photo when it comes in..
Maybe a bath towel with her initials or name embroidered on it.
Our daughters elem school mascot was the Scotties so we were always on the looked out for tops, hats, gloves.. things with Scotties on them..
I do agree children love the US mail.. anytime you can address and mail a letter to them.. that is very exciting.
