DS has always got blue lips whenever it is slightly colder than normal from being a young baby.
I never thought much of it but my sis keeps urging me to go to the GP about it.
It only happens if there is a chill in the air or if he has been outside and it is cold. But they go very purple. Even in the house if he just has a t-shirt on and the heating isn't on they go bluey.
He displays no other signs of being cold other than cold hands.
Do you think it is just a reaction to differences in heat or should I take him to GP? What else could it be?
