I haven't dealt with this but I know that every time we bring the kids to the vet that this is something they check for. Grade 4 is pretty bad for your girl being so young. If you trust your vet I think you'll get your second opinion with the specialist. Aww your baby will feel so much better afterwards. I know it'll be harder on you though - it always is. I can't stand it if mine just don't feel well. Good Luck and keep us posted!
