During the week I am only able to nurse the babes 2-3 times a day because of work and they get cows milk to replace the missed nursing sessions. On the weekend, we go to exclusive nursing, each baby nursing 4-5 times. We had their 18 month appt and the doc was once again not happy with their weight gains. so my question is this: on the weekends To add calories, should I give cows milk between nurses instead of their water sippys? What does everyone else do? I'm just trying to add as many calories as possible but will they be miked out?
