babygros for big newborns?

[BigBoPeep]

I'm finding that my baby's (4wks, 11lb a week ago, but seemingly with long, long legs!?) out of 'newborn' babygros, but not yet into the ones for 3-6mo. Does anybody know of any places that do big newborn clothes to plug the gap? Not enitrely sure what I'm going to put her in soon...

0-3 size??
I think m&s come up big too

Next ones seem to fit longer.

Also h&m do 0-2 & 2-4 month sizes so they're quit good for in between sizes.

0-3 months normally does up to about 14lbs

thanks for the ideas people!
