It's midnight here. Cannot get my brother on the phone to ask what he would prefer me do.

Nephew's breathing......seems deep yet shallow. He is asleep, but it bothered me so I put my hand on his chest. I can feel his heart beat and it seems a little faster than his 3-yr-old sister. But it seems to be pounding though.

I have his medical card, but do not know if I should take him or am I the overly cautious, childless aunt?

His temp. was 100.2 about six hours ago and dropped to 98.8 about two hours ago. Asthma runs in the family. His sister has it.
Thank you.
