I have a 3 week old that sleeps basically all the time except while eating. I mean he might be up 5-10 minutes after eating without crying a couple time a day but really it is eat and go back to bed. I have noticed the last two days that if he cries for even 2-3 minutes he gets really sweaty on his head and most the time when I pick him up he will just pass out in my arms immediately. This is concerning me because I have a 6 yr old that was born with a large VSD that resulted in him having 2 open heart surgeries and have since found out that he has a genetic issue that I'm the carrier of. Pediatrician says she doesn't hear a heart murmur. Am I justfied in calling the pediatrician tommorrow and ask that my 3week old get checked out?
