Yes, we have noticed it weeks ago, but assumed it was because of the hot weather or because he has such a large one that it just sinks in more (less to support the skin underneath).
He has breastmilk caused janudice and reflux.
Its sinks in about - i dunno, say 3 -4 mm? Its not always obvious, such as if he is lying down (GP said thats cause of the pressure).
