What do you mean, since you had your daughter? What kinds of problems are you actually having?
Are you talking about having a bulge? In that case, what you have is actually probably diastasis. You can look it up online to learn exercises to remedy it.
If you're constipated, you probably just need more fiber, water and exercise, and less meat. (Best way to prevent needing a colon cleanse is not eating meat/dairy and white flour products, and in their place, eating plenty of fiber.) Since AMericans are chronically dehydrated (as a culture we drink far too little water), and since busy moms of babies forget to take care of themselves, this is probably a large part of your problem. Believe me, not increasing your water and increasing your fiber is not going to help a whole lot.
Bonus to drinking plenty of water: your fine lines/wrinkles smooth out (well, probably not much of a concern for you yet)!
One great herbal cleanse is Gaia Herbal out of North Carolina. My husband after doing it felt better than he had since he was a teenager. But you have to be disciplined. Everything of value takes earning it :) Best way to approach it is to plan ahead: shop for cleanse-friendly foods and snacks that fulfill your cravings without breaking the diet.
Private message me, though. You could be having any number of problems with any number of causes. I don't want to just tell you about digestive cleansing without knowing what's actually going on.
