Is it dangerous if i feel my baby's heart rate goes up a lot when he cries?

No: It is very normal for your baby's heart rate to elevate when he is fussy. As long as his color appears to be normal (i.e. Lips remain pink in color, never dusky, blue or purple), your baby is having good circulation. Once your baby calms down, the heart rate should go back down to it's normal pace.

Yes: It's normal for a baby's heart rate to go up when the baby is upset and crying. Babies' hearts beat faster than adult hearts, even when the baby is quiet. A heart rate of 140 is normal for a crying baby and won't hurt your baby's heart. If his heart rate stays fast (eg. Over 180 or 200 beats in a minute) when he's quiet, then you should tell his doctor. A heart rate that fast could mean a problem.

No: A baby's heart rate is normally high--around 120 to 160 beats per minute--and it often goes as high as 220 beats per minute with crying. Anything over 220 is abnormally high, especially if it doesn't come down to normal when the crying stops. Call your baby's doctor if his heart rate is greater than 220 beats/minute (although it's hard to count it when it's that high!).
