1. The golden rule is you need one cover to 3-4 Inserts. Start with 3 and see how you go. Your baby might be a big and constant piddle machine.
2. Rotate 2 Covers through out the day. Hang the cover you are not using over your change table. This only applies if the cover is damp from wee. If the cover is soiled, then you need new one.
3. You really only need 6-8 covers for full time use or 3-4 for part time use. This gives you enough for the blowouts, washing and drying cycle.
6. You can sometimes leave the inserts snapped together to make washing easier and quicker.
