HELP! Baby squirrel is bleeding from nose, opening mouth as if gasping for air.

[Spanky]

She weighs 264 grams as of this morning and I'm using Espilac powdered milk. I feed her every three hours and about 3ml and a half.

Is she eating any solids... and do you know how old she is?

3ml is way too llitte, I am attaching a feeding chart. They should be fed 5-7% of body weight so for a 264gm squirrel that would be 13- 18ml each feeding. And every 3 hours for s 264grams squirrel is too often. I am attaching a cheat sheet for feeding amounts. SquirrelBoard Feeding CheatSheet.pdf

As for the bloated tummy...

1) Esbilac should be mixed up a few hours before feeding, stored in the fridge after mixing and discarded after about 36 - 48 hours... so only make up about 1.5 - 2 days of feeding.
2) Formula that has been heated for feeding but not used should be discarded; never reheat previously heated formula.
3) Once opened, the powder should be stored in the freezer (or fridge). If left out at room temp it will go bad (rancid) in a matter of days
