Any great way to loose stomach fat?

My daughter will be turning two in the nexty few months and I have been unable to loose the belly fat that I got while I was pregnat. Is there anyway to make that muscle stronger or to make the loose skin go away with out lypo or a tummy tuck. I know people will say exercise be does it really work. Are there any mother’s or anyone in the simular situation give me any ideas on how to get my sexy back.
