We switched from newborn to Size 1 when we were getting a lot of blow outs. We noticed the diapers seemed tighter around her middle too.
Maybe we are idiots, but we learned the hard way - when going up in diaper size, you need to put the elastic much tighter - we had to overlap it a little when we first switched to size 1. We had a few blow outs when she was kind of inbetween sizes but I think after a few days, she gained just enough and we realized to put the diaper tighter and we were good to go.
