Hi all, I adopted my two 10 week old babies 2 1/2 weeks ago and they've had URI's. The girl moreso than they boy. He's almost completely cured, she's still sniffling and sneezing a bit. This morning, when I was feeding her the antibiotic drops, I noticed a little smudge of blood beside her nostril. Why?? And why is she taking sooo long to heal?? Please help with any ideas or suggestions!
