yes, these wraps are always one size fits all, there are ways to wrap so that baby can look around and still have head supported if your lo is too little to really hold his own head well. My 7 week old is the same way and if he's not sleeping wants to be seeing everything. I've got a few of these (well, I have two moby's and one baby bundler but they are just different brands of the same wrap basically). great auction!
oh, they give so much fabric because they work with all size mamas, plus can be used with single babies or twins or toddler + baby with different holds. and plus as baby(ies) grow to accomidate and still have enough to work with easily =) they really are the most versatile of wraps because of all the different positions and options of use.
I agree they are awesome, and OS fits all. I am a plus size mommy (size 24) and I can wear the Sleepy wrap with my 19.5lb 17mo old daughter in it and still wrap it around my waist twice and still be comfy. If I didn't just get one a couple weeks back I'd be all over this, but its the same color I have lol. This is awesome. Everyone bid :p
