Sucking my LEFT thumb!!!

Today we were waiting to get the girls from school. I look back to see Sammy sucking his left thumb. I was the happiest about him supinating to do it (or at least to neutral......). He has sucked his left hand before, but not for a really long time. Each morning I find his paci outside of his crib, so maybe he is sucking his thumb in the middle of the night. One small step for mankind a GIANT step for a hemi kid. LOL!!!!
