Just for sharing. My daughter has this habit of pulling her hair to get herself to sleep, she did this from 4 months old and sometimes she ask us to do it for her too. Anyone else to share habits of your LO? :)

My 6 month old currently pulls MY hair to sleep! When she's nursing, her free hand just goes around grabbing whatever she can get her hands on including my nose, lips, chin, chest and hair. I've often got fingernail marks in those areas.
