Since my son was 10 months old his hands and feet turn blue and get very cold off and on through the day. We have gone to the doctors office, seen 4 different doctors, none of them can tell me why. they say he'll grow out of it, or dress him warmer. Just before his 1st birthday we were eating breakfast and his hands and feet were blue. But as i feed him his eggs i felt this lips were cold. his tongue and lips were blue and he was shivering. i took him into the doctors again, saw a 5th doctor, still no answers. He is 13 months now, and still turning blue. We live in Iowa, so it is cold here, but the house is 68F, new windows so not to drafty. If anyone has a suggestion on what to do, or has this problem with there child please let me know. Thank you.
