Grocery Store ABC's

So, a couple of awesome things about this post;
1. It's educational
2. It keeps your child/children busy and in the shopping cart while you shop, and,
3. it involves stickers, so they'll love it!
Last year, when my son was about 2 1/2, I wanted to find a new way to teach him his ABC's.  Whenever we would go grocery shopping, he would hold onto my list and pretend to 'read' it, and help me shop.  I thought it would be cute for him to have his own 'list'.  My Grocery Store ABC's idea was born!  Each week before we would go shopping I would draw a few pictures of things that started with the letter we were on.  While we were shopping my son would have to point out the items on 'his grocery list' (as he called it), and then he got to pick out a sticker to place by the item he found.  He was also doing pretty well recognizing letters, so I would show him the letter we were looking for, and if he found it in a word on a label, or anywhere else, he got an extra sticker on his paper.  He loved searching for letters, and I was really surprised at how well he was paying attention to words and looking around.
By the way, I am such an awesome artist ;) don't you think?
