The pictures are just toooo cute!!
Sounds like it's time to keep searching for a vet! It's hard to find a good one but it's probably the most important thing you can do for your baby. Perhaps there's a "teaching" veterinary hospital near you or another way I find good information sometimes is to watch for people who also have very small pets and ask them about vets, etc. in the area. Sometimes you get useful information and sometimes you "draw a blank"!
It's always interesting!
