can you pls tell us how many months it has been since your wife delivered?

some people i know use belly band to tie their belly. it dost not go back on its own. ur wife needs to do some sports. she should maybe start with a 3-5 days a week walk on the cornich or so.

personally, it took me at least 4 months to get back in shape. ( i walked every day at least an hour or 2)

if your wife is still breast feeding, pls advice her not to worry much about loosing weight, cus most important is to eat healthy and breast feed the baby with healthy breast milk.

good luck
