Cloth Diapers = Not Stretchy

Hello there! Today I am hoping that some of you use cloth diapers. We do. But we have reached an impasse, and I need some expertise. First, some background. We started out with Tate using the Bummis cloth diaper system. And we love it. The diapers are so, so absorbent. And they wash up beautifully. And I really love folding them when they are all warm from the drier. But... they don't fit anymore. We bought two sizes- the infant size and the baby size. The infant size worked wonderfully- a little big when Tate was born, but we just folded them over a bit, and it was fine. But the infant size is now, officially, too small (despite our stretching, the way you do with a t-shirt that clings a little too much... You know what I mean, right? Right.) So we tried to move up to the baby size and... well... I couldn't help but laugh. They were HUGE. So big. I don't think we could have fit any of his clothes over the giant, bulky diaper. Truly, I think I could use them as towels. So if you use cloth diapers- any advice? What do you do when you are "between sizes"? P.S. We have also used (and loved!) these Snappi Diaper Fasteners and have faced the same problem. We have had to move up to the "toddler" size to stretch across Tate's adorable and chubby belly, and they are almost too small already... is it true that chunky babies thin down once they learn to crawl and that these fasteners might fit better then? photo via weheartit
