I do not know what it is, but my son has a thing for licking me. He is now 11 weeks old and for the past few weeks he has been doing this. He did in front of the health visitor, as well. He just sat there and slurped away. He does this even after he's had his bottle. Whenever he is on my shoulder and there is bare skin or near my bare arm, he opens his mouth wide and licks. Last night he went one step further and not only licked, but made slurping noises and I felt him nibbling me!!! The OH said when I am not here Sebastian is perfectly fine and settles well. As soon as I am home Sebastian acts up and wants to be with me all the time. Even when the OH is feeding him Sebastian will watch me. Does anyone else experience this? Is my son turning into a mommy cannibal?
