Need advice I have three days to stop breastfeeding because it seems I have one medical problem after another my son is two we made it two years and I’m happy with that but I now need to stop so I can take the medication I need to and get the things done I need to. Looking for advice to make this transition as smoothly as possible for me and my son I have him liking his sippy and chocolate milk but I also want to make sure I don’t get egorged either just looking for tips and tricks when suddenly stopping breastfeeding I’m already cutting out nap time and morning feedings going to try night feedings in the next three days..
