Looks like Ava is going to be a thumb sucker. We thought she would from the beginning. When she was born she kept trying to fit her thumb in her mouth. We tried to keep her from it (Dave had a little problem giving up his thumb as a child so he didn’t want her to start the habit). However, she clearly prefers it over pacifiers or anything else. She has discovered her hands now, and with that comes the thumb! I guess the good thing about it is that we don’t have to worry about her losing a “binky”.
