I got given a load of these on sunday. I have washed them all including the wraps i was given. The wraps have a size in them but I've noticed that the nappies don't! So does that mean that they are the same size as the wraps?
I got a couple pre-loved to try (sound like they are the same) and they are a one size fits most. Where there are 2 rows of snaps at the front you fold it down for smaller babies to decrease the rise. Here's the demo I found that showed me how to use them. It is a bit long winded but it did help me. Hopefully you'll be able to see if it's the same style? https://m.youtube.com/watch?v=wGlKVYgXC7Y
What a great score for your stash ! My understanding is that they are very very similar to Mother Ease One Size nappies, I looked at them when I was first dipping my toe into cloth before Louis was born. I didn't end up getting any but they would be a great workhorse nappy that will do you a good long time
They are the same as the ones on the demo. I will have to get some practice in before little man is born, I also got given some all-in-ones, but they are far too girlie! Lol
You can fold them down when baby is little but they are quite bulky. When baby's bigger you can popper in the booster for a bit of extra absorbancy. I sold mine to someone who wanted to experiment with dying them -they turned out really well. I hope they work for you.
