When did your newborn fit into XS AIO?

[b-girl]

We have a small stash of various xs AIO and were planning to use them for a day or two (daytime) and then order more of our favorite to complete the stash. But.... we tried using them one day last week and they rubbed on his cord stump so much it irritated the stump and caused a little bleeding. So now we're back to sposies.

Has this happened to anyone else? Right now we're not trying them again until the cord stump falls off Ugh, we're both sick of the sposies already!

I think it depends on the brand of dipes. Some are designed to go under the cord stump. If yours irritate it, I would just try again after. That's too bad that you can't use them yet!
