I love the water and want to introduce DS to swimming soon by enrolling him in waterbaby classes! I hear great things about cloth swim diapers versus the disposable ones. So let me know what all I need to know about them!

For instance, do I need to buy inserts for the swim diapers or can he just wear the swim diaper and be good to go? Any brand preferences and is their sizing true to size? etc. Thanks ladies!!
