would you buy newborn aio's?

luvbeingmom

this will be the 2nd baby that i'm cd'ing. i started my dd#1 when she was around 8mos old. my stash is all grobaby, and i definitely want to stick to the grovia brand. i'm comfortable with it, and have had no issues whatsoever with them.

dd#2 is due this june and i was just looking at their package of 12 newborn aio's and was considering it. i want to build up my stash a little bit because there will probably be a small overlap with two in diapers but now i'm slightly conflicted.

i don't have any aio's, but am willing to give it a try. and i like the idea for the newborn aio's, but now i'm thinking getting that could be a waste and i should just get the one size aio's. 

does it really make a difference? i believe the one size aio's go from 5-35lbs anyway and my kids have averaged around 7lbs newborn weight... 

thanks!
