I switched very slowly over the course of a few weels. I stopped completely about a week after she turned 3 months. My milk dried up in a couple weeks. I am using Nestle Goodstart. That's what I used for my first baby, so I just stuck to that. It was a very easy transition and no problems with either of us!!
WTG on making it 3 months, though!! That's a great accomplishment. That was mt goaltoo and so when I decided to switch I felt very good about my decision.
