We used PS with our older son (OS wasn't created yet) up until he was out of diapers. Â We never needed larger than a M, which was awesome. Â After prefolds/covers in the early days, the M PS was all he needed.Â
Â
Now we use both PS and OS (along with a mix of other dipes) with our youngest and I like both. Â I love that the OS has the replaceable elastic. Â My initial stash, after being used by 2 kids and being stored for a while, ended up with shot elastic and I couldn't use them (still need to get those to a mama who can sew!). Â I like the idea of being able to replace the elastic and get much more use out of the OS. As for fit, we like them both - have no complaints. Â

Washing routine is the same. Â
