I realized too late I should have made him stop sooner too. I just felt bad about how hard it was, I mean, he'd had this habit since birth! Every once in a great while I'll see him with the tip of his thumb resting on his bottom lip, but he's stopped for the most part. I did forward your blog and etsy shop onto my SIL, she's got 2 thumbsuckers right now, 3 and almost 5.
