Sal, just be careful with using the coloxyl, I was using it with Hannah and my SIL who is a Dr said it is not a good thing to do as it can make their bowel get "lazy' and cause problems later on with bowel control. She was really worried about us using it.

One thing we found that helped was to be really pedantic about making formula, especially about the water temp as it made a big difference.

Good luck.
