Crisitana does not like binkies. We have tried 3 different brands as well as types of pacifiers and she spits them all out. But she definitely loves her fist. Even when she's on tummy time with both arms supporting her upper body she will go for her fist and of course looses her balance and goes head first into the ground (don't worry, it happens in slow motion so it does not hurt her). I think as her fingers get bigger she'll eventually move on to her thumb but for now, with every part of her still so tiny, she enjoys sticking her entire fist in her mouth.
