ok i will try to change the food for the girls and see if it helps the babys breath she has always had it so I can try the new food any suggestions on what brand and how to introduce it to them.I now use a auto feeder the older girls were getting a little fat so the auto kepps weight down.I hope that it is the food because i am worried about the baby now.like I said before she has no other signs of being sick except the breath so any advice on this will help thanks
