My baby is in between diaper size 2 and 3?

where i live at least, huggies sizes tend to be on the small side as far as brands go, try the size 3 in those and you'll probably find they fit ok.. Im not sure where you are but im in Australia and here diapers come in newborn, infant, crawler, toddler, walker and junior.. so im just assuming a size 3 equates to the 'crawler' size we have.
