Touched by NatureUnisex Baby Organic Cotton Bodysuits

Is the 6-9 months closer to 6 month size or closer to 9 months? My daughter wears 6 months Carter's right now- trying to get the next size up...

do they have metal snaps?

what color is the stitching on the plain white onesies?

Does the price include all of the baby bodysuits pictured under each option (3, 5, etc)?
