Mckenzie was just a few months old when we noticed the temp changes in her arm, especially in the summer when she would sit by the window in the car and get a sunburn. Now, I make sure that she has sunscreen on her arm at all times in the summer. She is 5 now but has never said if her arm is cold or hot. I've heard BPI children can have a very high tolerance for pain and sensitivity. Now that our winter is almost over here in Idaho, I'll look into the warmers for next winter.
Thanks for the info!
