Healthy baby and ok during breastfeeding now at 4 slow weight gaining?

Question not clear. I am not sure I understand the question totally. If you are saying now that you are slowing gaining weight, it is probably related to your calorie intake, activity level and not having an increased metabolism if not nursing now. Make sure to eat right, limit sodas and sports drinks, avoid second helpings and snacks and me as active as you can be. Try a jogging baby stroller to help.
