hmmm.... Matilda has one. Never thought anything about it. Have had a good look & its pretty deep, but she's been checked over by so many paediatricians & doctors because of reflux I would have thought someone would have said something... they checked every little bit of her with me watching so I know they've seen it.

Kathryn I hope the scan goes well! I may make a note of it to get hers checked and "on record".
