With DD1, we began the weaning process around a year, but she had always gone back and forth between the breast and bottle, and had dabbled in some occasional formula. So around a year, we just did the "don't offer don't refuse" and switched to cow's milk bottles with her, which ended altogether around 18 months.
Flash forward to now -- DD2 is going to be 1 next week and we are down to 3 nursings a day. My question: For exclusive BF moms who weaned around a year, did you just use sippy cups of milk? I plan to gradually drop feedings over the next few months and use the "don't offer or refuse" method again.
