i have noticed that mmy dd has a lump that sticks out under her ribs when she lies on her back and appears to hold her breath whilst crossing her legs and arms. we thought at first she was trying to do a poo but she seems to do it in protest and she does it quite regularly and now i have noticed the lump, i'm quite concerned.The lump isnt there any other time and doesnt seem to bother her when you touch it, anyone else experienced similar?
