About 5/6, more if she is having one of her twice-weekly three poos a day! And a night nappy, sometimes needs a change if she poos before we manage to get her in bed
Iona uses at least 8 a day and Findlay uses at least 6 in the day and 1-2 night nappies although depending on the effect his laxatives have he can use a lot more.
About 6 or 7 during the day and usually 1 night nappy (although it can be 2 if he wakes up uncomfortable). He's another who can do between 1 and 4 poos a day! He's also a very heavy wetter, but just learning to hold his bladder, so he can go 2 hours with a dry nappy and then 1 pee and it's soaked!
