With DS - I bled/shed so heavily the first 4 days I was using the ultra-super sposie pads and changing them every hour during the day and every couple of hours at night. After that I switched to just "light days" pads for about 2 weeks and then I was done. I don't think I lost any more/less than average - it was just over a very short time period. After the 2nd day, I actually used Depends for the next two days so I didn't leak through.
I'm tempted to do cloth this time around, but if I do a repeat, I don't think I'll have enough for 12+ changes a day with really heavy flow. I hate sposie pads - some make me break out is hives. (My son also reacts this way to most sposie diapers). I'd appreciate any ideas for super-capacity cloth, short of seriously bulking up with prefolds. I've used cloth pads for my usually light periods.
