My neighbours asked me to look at her 7 month old. His lower ribs are protruding and he seems to have a dip in the middle chest area. The dip is actually quite pronounced when he draws a deep breath ie to cry? He is a healthy looking adorable little boy with a very anxious Mummy.
Hi.what you are describing is classical of a physiological condition called - rectus excavated - wherein the chest in the middle of the sternum will be dipping in, and otherwise the kid will be normal. Sometimes this can be a tell-tale sign of severe respiratory distress in early infancy and otherwise doesn't harm the baby any way. But if she is really worried, ask her to show to a pediatrician and get things sorted out. Regars -
