I’m new to cloth diapers so I don’t know all the lingo. I’m using Alva baby diapers they are the kind that you insert a pad into a pocket so they pee on the cover and it has to be washed every diaper change. Each diaper came with two inserts each. My babies (twins) are 7 weeks old am I supposed to be putting both inserts in each diaper at the same time? They don’t seem to have any leaks with just one pad. Is this for when they are older and peeing more? Or are these just for when the insert gets worn out to replace it? Probably a dumb question but I just have a whole drawer of these inserts that I don’t use at all.
