Diaper question

I have a ton of size 3 diapers! Huggies mover’s, huggies snug and dry, and huggies overnight. And they are all opened and I have used quite a few diapers from each one! They have been fitting my baby pretty tight around the waste and I’m thinking it’s time to size up. I don’t want all of those diapers going to waste and especially the money I spent on them!

Is there anything I can do?
