Sizing help??!

Tymber

So my baby girl

is now too big (chubby legs) for her newborn cloth diapers (we were using gdiapers with cloth inserts) but too small for onesize the all in ones I've purchased. Right now we are using prefolds with covers, but they seem way bulky on her she is only 6lbs 13 oz!

Anyone else have a baby in between sizes? suggestions?
