Just wondering if anyone has tried the Birth to Potty Bamboozles (with poppers) and found them really small? I recently got one secondhand and I can barely squeeze my nearly 9mo little boy into it! It neat and trim alright, but it's just so small around the waist! Can't see it's good for very much really. Didn't know if it was possibly a bad batch, or if this is just normal. Certainly much smaller than a size 2 one.
