I never had problems with hypoglycemia when my pups were babies. I think what might have helped was I free feed. They always have access to food and water. When they are that small it might be a good idea to leave food and water down all the time for them to be able to eat and drink when they need to. I also gave them a treat every single morning when they went pee outside. This probably put enough in thier tiny tummies to tide them over. Im sorry your baby scared you. I would have been a mess if that happened to me also! Glad he's ok!
