I haven't had any other kids myself so I've never tried but hear such good things about binding. I found some by the sports brand Everlast on clearance for $5 each at Home Sense(but I know I've seen those at Sears for a very good price) and decided to buy those. They aren't natural materials which is the only downfall I can see, so far. I bought one men's and one woman's. The men's has velcro close and the women's zips, and they both seem like they will fit a decent range of sizes. I believe I purchased both in either O/S or XL but I was surprised that they appear that they will fit (I am not small in the first place, especially not when 35 weeks prego when I bought them)
