After five straight days Keith finally managed to get these yellow undies off of Carter!
I bought a pack of big boy underwear for them and had intended on using them for stocking stuffers. The moment they saw them they thought they were pretty cool and wanted to wear them. Since we were at Grandma's house, we just put them over their diapers. Since then Carter has not only wanted his underwear on at all times besides bath, he wants the yellow pair. We tried to sneak them away several times. Tried to convince him of a nice blue pair or a really cool red pair, but he demanded yellow. Hopefully he forgets about them tomorrow morning or else I need to go buy several pairs of yellow underwear. And if you ask him what color they are, without question he will get really excited and say "yellow, yellow undies". He's so proud of them!
