You dont need to tie ur tummy since u had CS. Tying it after 3 months wont have any effect again. Continue breastfeeding ur baby, it will go down but if u are not satisfied, once ur baby is a year u can start some tummy trimmer exercises. It works like magic, talking from experience. Also dont eat late night meal, it add more to d tummy fat. Avoid Sugar and junks too.
