Sam constantly reminds me of Linus from The Peanuts. He loves nothing better than to cuddle with a nice soft blanket or toy and he can’t keep his thumb out of his mouth. I was successful in keeping Scarlett from getting into that and we had to make Stella stop because she kept throwing up. No luck with Sam, but I’ve yet to see a mentally stable adult sucking their thumb, so we’ll get through it eventually. (First time parents should remember that with everything – like potty training – have you ever seen someone who doesn’t have mental issues who isn’t a potty trained adult?)
