Nursing

Baby is still nursing.  I think that is why the females from the "Gang of Four' seem to be jealous of Baby.

As you can see even after five months Momma seems to have plenty of milk.

Here is a 1:34 video of Baby nursing.   Momma is pretty calm, even when Baby is hitting against her milk bag.
