I'm guilty of "convincing" my kids to like the presents I already bought for them. My five year old has no idea what he really likes, and what he would actually play with. I made the mistake of buying him some of the things he asked for last year, even though I had a suspicion that he really wouldn't like them, and guess what, he never played with them!
This year he keeps asking for the ridiculous
crayola crayon carver, seriously?? you can write words on crayons? He would do one or two and the novelty would wear off and it would go in the closet. It is labeled 8 and up, so I told him that Santa can't bring it to him because he isn't 8 yet. He is going to love the legos I bought him, much, much more!
