my daughter has done this since she was born and the doc never witnessed her do it so he said she was fine.
But every time b4 she goes to sleep she crosses her legs stretches out her arms and has to grab something. as she grunts and tightens her legs together if you touch her or move her she'll cry and get mad. shes only 15 months old and from my research it sounds like a rare case of infantory masturbatory. i dunno tho right after she done with that she'll fall right to sleep whether laying down or in her car seat.?? and ideas or comments on this would be greatly appreciated
