T.M.
I have two daughters (22 1/2 and 6 1/2 mths old). My oldest is all I have to offer...I started transitioning her by mising formaula and milk so the taste becomes familiar to her and then one day she asked for milk and I just gave her regular milk in a sippy cup and that was it no problem. I only mixed the two for a day or two. Pretty easy transition...my todller now prefers cows milk over formula and will not take formula unless extremely tired. Good luck!
