The reason BF helps youloose weight is because it takes about 500 cal extra per day to make and maintain a sustained milk supply. However, if your baby is only 8 weeks old, you really are only in the begining stages of having a sustainable supply, it takes anywhere from 46 weeks to get a good milk supply established.
In order to see any benefit of weight loss you really need to have an established supply for at least 6 months with exclusive BF being the best route. I would not really expect to see you show any noticeable weight loss form 8 weeks of BF.
That being said, I am a bit worried when you say you "wrapped up my girls". Are you trying to supress your milk supply with breast binding? This is not a good idea. The milk ducts can easily back up into ducts as far back as your arm pits and binding can also lead to mastitis, which you REALLY dont want to deal with! If you are trying to dry up your milk, try drinking several cups of Sage tea a day making it from regular sage you can get a tthe grocery store. It is better to find a fresh herb source like the Farmers Market maybe, but the dried herb works well too. For engorgement and painfull breasts while your milk is drying, you can put clean, washed green cabbage leaves in your bra to hlp relieve the discomfort. You can also express just enough milk to give you relief w/o bringing back the milk.
Milk works on supply and demand so it is really better to wean them over a period of a few weeks than trying to do it in a short amount of time. This will be much easier on you! BF is an emotional bond between mom and baby and you may notice your milk let down when he cries or you are snuggling and htis is normal, it just takes a while to dry up.
