I think i had about 5 packs of Boots fat pads and then a few packs of the slimline Boots maternity pads.
I had lochia for about 6 weeks i think, can't quite remember, but it was really light and nothing as bad as i was expecting!
I don't think it is recommended that you use normal towels like always etc as they can dry stitches out too quickly and can cause irritation.
You may well be glad of the extra padding initially!
