My 5 months old is outgrowing his cloth diapers

Didn't know this would happen this fast as I bought one size fits all. He is a big baby. I have a potty and I true elimination communication and not every time is successful. Feel like his diapers won't fit him long before he is able to go diaper free. They will go another 6 months or less probably but not all as we are closing the diapers on the last and second last button currently. He makes 5 months next week.

Are there any recommendations for extra large diapers for big babies? I don't want to end up using disposables when he is a year.
