dd1 (my third) was referred to a paediatrican at birth because of her extensive birthmarks. At the consultation she was very very thorough and checked her for everything, and I went away happy, but when I got her report there was a phrase in it which puzzled me- she wrote 'mouths her lower lip a lot which is a possible cause for concern'. DD (14 weeks then, 5 months now)does have a habit of sticking her tongue out over her lower lip a lot (sorry, it's really hard to describe in words), but in other ways I haven't seen anything to cause me any alarm. She is a bit behind her brothers at the same age, but I just assumed all babies develop at different speeds. I have left several messages with her secretary (the paed's, not dd's ), but no answer yet and I am curious. Any medical folk out there care to venture an opinion? HV was (as always) v non committal.
