I share your frustration. We have had some bad experiences with kids and the result is Max and Teddy don't trust them. They don't like babies in strollers, but babies out of the stroller they ignore.

I agree with Gracielove that training with properly behaved kids is the only way to overcome this behavior.

As for growling at the baby, the only thing I can suggest is to wear out Bailey before you meet up with your friend with the baby. Drain her of energy with a walk or vigorous play. Do something fun before and after you see the baby. Try to associate a yummy treat like a chew with the baby's visit (although don't forget to supervise Bailey with the chew).
