OsoCozy - Indian Cotton - Prefold Cloth Nappies Infant 4x6x4 (Dozen)

Q: I'm looking for PREMIUM infant 4x6x4s and dont see the option listed. Are they the infant diapers with YELLOW or BLUE stitching?

I think you want the 4x8x4 infant diapers. Search for "OsoCozy - Indian Cotton - Prefold Cloth Diapers Premium 4x8x4". They have blue stitching.

Q: How big is the infant 4x6x4 vs the medium 4x6x4?

My daughter wore the infant size until she was a little over 5 months old and about 14-15 pounds. They were really getting to be too small at that point, and it was a relief to switch to the medium size. She is now 9 months old and still wearing the medium size. There seems to be a little bit of variation in the individual diapers, although I'm not sure if it is due to how they're made or to how they fluff/shrink in the wash. Right now, a few of her medium-size diapers are starting to seem a bit small, but most of them still seem roomy enough.
