my son has a congenial heart defect. he is now 16 months old. well tonight while eating he passed out. or at least that's what it seemed like to me. first i shook him gently then i lightly tapped his cheeks and that woke him. then just a few minutes later i took him to change his diaper and he passed out or fell asleep again. i have woken him every hour just to be sure and when he stay up everything seems noraml now. do you think the i am over reacting or could this be a sign that his heart is giving him trouble? also if anyone knows what the normal heart and pule rate is for a child of 16 months i would really appreciate it. I had it in paper work and it is missing now.
