My daughter is 3 months old and is still desparately trying to find her thumb. It doesn't help that she tucks it behind her finger! She is using a dummy to go to sleep but I would be much happier for her to suck her thumb as she cries in the night when she is trying to find it again. I wonder also if she will take to her thumb over her dummy. Will she find her thumb soon?! Has anyone else's baby gone from a dummy to a thumb?
