As the title really. Our 15 month old DS's lips sometimes look as if they are bruised, and have blue spots. He bit his lip last week so I assumed it was that but tonight his top lip was the same too. Has anyone experienced this? It seems to be more prominent sometimes and barely visible others. He's healthy enough otherwise, so I don't want to be one of those hypochondriac mothers who rushes to the doctors every five minutes, but at the same time it doesn't seem normal either. Any ideas/suggestions welcome.
