To me a baby is a baby is a baby, human or animal and they have to be fed on schedule. Jay is right, you will have to feed the baby birds on a set schedule, just like a human newborn no exceptions if you want them to grow strong and healthy. I know you can do this. It is a sacrifice that when you brought the babies home you committed to. You can do this!!! Dave and Jay will help you just ask. I have all the faith in the world in you Tanya.
