Re: changing to formula
What is passing motion? Was she breastfed and this is the first time she has had formula? If so, it could be a number of things. First of all, when mixing a babies bottle, never shake it. Make sure you stir it. Also, there are special types of bottles that cut down on the amount of air that the baby ingests during feeding. You could try one of those. Also, it could be a lactose problem. For my second and third child, I had to use soy formula after breastfeeding. Regular formula made both of them very sick. So you could try that too. Make sure your burping her good also. Good luck.
