What I did when my RB Mytsi had babies and they got old enough to eat was touch a little bit on the food on their noses so it stuck and they had to lick it off. After doing this a few times they would go looking for the food as they liked the taste and it was new to them I guess. So before long they were nursing less and less and eating more and more on their own. DOn't be the least bit surprised if Momma gobbles up the food as she wants her baby to stay her baby and dependant on her but baby will learn quickly to get her share and momma will loosen up and allow her to do so.
