Blue fingers When crying and sick?

I'd call the pediatrician to be sure but mine said ER worthy of that happens. Indicates low oxygen levels.

His oxygen levels are either low or his blood isn't circulating well enough in that area.. neither of which are good.

Id be very concerned.

Yeah that's a circulation issue. In my EMT training that was a little red flag. I'd have my baby checked out even if it is nothing.

I'd go in. Asap. I'd need reassurance
