Cloth diaper inserts

Tasha

Hi everyone wondering if anyone could give me insight on how long their cloth diaper inserts lasted before they replaced them and got new ones?? My daughter is now 18 months we have been cloth diapering since she was a baby but I’ve noticed that her microfiber Alva Baby inserts are just not as fresh as they used to be and I’m wondering is it just time for new?? Or do I need to come up with a better wash routine? I got cloth diapers in order to cut back on cost and know they are great for the environment in comparison to disposables. So I just wanted to make sure I got the full use out of them before I went out to buy more inserts.
