I think we have a little thumbsucker on our hands! I'm THRILLED, really, as we will always have this portable soothing device on-hand (ha!) and won't have to make sure we have a pacifier on us at all times. Maggie LOVED her bink, if you remember, so this is a new experience for us. As hard as some days have been lately, I just love him to pieces and have found small joys in watching him discover his thumb.
