I think I might have some finger suckers

I keep catching Porter and Kamryn sucking their fingers. Yesterday I went in to get Porter up from his nap and he was just as happy as can be sucking his thumb. On Saturday I put Kamryn on the floor so I could help the kids do a few things and she was pitching a big fit, next thing I know I turned around and she had 2 fingers in her mouth sucking away. Crazy! I keep taking the fingers out and putting binkies in but at night neither one takes a binky so I'm now wondering if they are sleeping so well because they are sucking their fingers. I snapped some pictures because I have to admit, it's stinking cute!
