Poor baby Reese

Poor Reese just can't seem to catch a break...
she had a sinus infection, so the Dr put her on antibiotics, to get rid of it .But the have caused her to have constant diarrhea, which had caused her to develop the worst diaper rash! We are talking bleeding diaper rash. So needless to say she screams hysterically every time she has her diaper changed, which is all the time now. But I got some new creams from the dr today, so fingers crossed it goes away soon. She will be done with the ammox on Wednesday!
On top of all that I noticed last night, that she has cut not one, not two, but THREE teeth over night! Poor thing! So she now has 4 chompers on the bottom, and 3 on the top. WOW
Oh and I forgot to mention that she now bites. How do I stop this??
