Hi Koalarie,
Sometimes when baby crying, they will feel cold. My bb also. I let him crying because i don;t let him use to it that when he cry ,we will carry him. After 5-10 minits, when i carry him, his whole body feel cold. Maybe is like that, bb crying will feel cold.
Actually can let bb crying up to 15 minits. If he still crying badly than u carry him. Don;t worry to carry him immediately, if not next time u will suffer. Everytime cry than want carry.By the way,of coures heart will pain.
When baby crying, u need to see whether is urine full, hungry or the carry way is it correct..Sometimes baby don;t like the position that u carry. Same as my baby, when he crying, i carry him, he still cry, than i change to another position , he still cry, so i keep change patern .In the end, he finally stop crying and after that fall asleep.
If u worry bb got wind, u can apply"ru yi you".
I am not sure what is the systom of colic...if u using avent bottle, should be don;t have this problem.
