Hello there. My son was 14+ months old when I had my VSG. I'm 18months post-op and he still nurses. We had zero issues. He was eating solids but still got a good source of his nutrition from me. Don't let anyone tell you that it's not possible. Wrong! Obviously, you must make sure you get adequate hydration/nutrition. Go up to the search feature and type in wls and breastfeeding. There was a lady who had bf'ing twins when she had wls. Good luck!
