My 10 week old pup is hypoglycemic also....you can search all my posts many are about hypoglycemia, and the responses are great help! Do you cage her at night? That is one of the most stressful things you can do says my vet. They are pack animals, and being seperated brings on a lot of stress. I give nutrical 6 times a day just lil bb size bites he licks it right off the tube. I do it just to make sure he has something in him at all times. WHat food is your baby on? I had many reccomendations for Innova EVO he started EVO friday and he seems to be doing great! My 2 year old yorkie also welcomed the new food.
I think your doing everything right, and tongues get slightly pale after sleeping in any dog, blood doesnt flow as much to mouth when sleeping....I'd keep an eye on it, but I really think ur doing great!
