Be cautious and read specs and reviews since the size and age ranges of all diapers vary greatly based on your child’s size and build. Most one size diapers claim to fit anywhere from 6 to 8 pounds all the way up to 30-40 pounds. I didn’t start cloth diapering until over 4 months and my son is a small at 12ish months now, so I can’t speak too much on the sizing, however, I’ve heard many people say that most one-size diapers don’t fit well until the baby is close to 10 pounds and didn’t always last through potty training.
Velcro or Snaps?
Another option is a closureless diaper. With these you would need to pin them or use a Snappi.
Soakers can be made from cotton, OBF, OBV, microfiber, hemp, zorb and more. Microfiber, and zorb should be within the soaker and not touching the baby’s skin.
