I recently realized that it was pointless to hang on to all those lovely little suits I bought for church, little tops for play and jeans (that were wearing out anyway...thrift store finds...the only way I can afford Levi's). I'd regained some weight and those darling small-size outfits just weren't motivating me to slow down on the eating (was exercising very faithfully). Then it occurred to me, why did I need those particular outfits? I needed certain things (like a black skirt and/or pants and white top for our choir's special concerts) that could go anywhere (like funerals, special dinners and church events). So I really and ruthlessly went through my collection and sent a bunch of nice things to the DAV, some went to a lady who had lost everything in a fire...now my wardrobe is much smaller, more versatile and in a size (or size range) that better fits my post-menopausal figure. I feel more comfortable with these clothes and think I look better. And now I'm better able to get a better handle on the eating, too.
FWIW, my body didn't change that much from childbearing. After I lost all the baby weight (really fast after our second daughter...from chasing after two little ones I guess), I went right back to being a nearly flat-chested, no waste little ruler, down to my high school weight and everything...now, 30 years on, I'd be happy just to be at a healthy weight, with the spare tire deflated some...in fact my middle-aged middle is my biggest problem in looking just right in my clothes. You may well find that your body has made some rather nice changes as the baby weight falls off...
Ditch all but the clothes you love too dearly...when you are back to a good "fighting" weight, you'll have so much fun buying all new things in a smaller size
Good luck, Kelly!!!
