Epi Kool & Kotex Overnight Pants

Hi mummies! First pregnancy here and have seen alot of reviews on how epi kool & kotex overnight pants can help with after vag delivery. Planning to standby some in case. How many is enough? I’ve heard not to get too many as epi kool is only needed for the first few days of soreness and kotex overnight pants is for heavy blood flow which will also only last for a few days before we can revert to normal sanitary pads? #firsttimemom #advicepls #firstbaby
