I know in humans that feeding too much to a person that is in late stages of starvation can kill them.
But in the animal world it might be a normal thing to go for long periods with out food.
To be on the safe side I would only feed 1 half of a stick a night. for a week or so.
Then as the baby starts to get filled out some then we will go form there.

I think baby steps is the best approach.
