Thanks for all the teething advice! I will definitely be using it!
After day four of refusing a bottle, my instincts told me this was not just teeth so I did take him into the doctor yesterday. She said he has a stomach bug! It explains the diarrhea and it's also super common for them to refuse a bottle when their have a bad tummy but be open to solids. I feel kind of bad for force feeding him!
The good news is that we haven't had a poop explosion since yesterday afternoon and he took a 9 oz bottle this morning...so I think we've turned the corner.
I appreciate it everyone...it's good to know I'm not alone!
