I just bought my first itti for my little boy.
Only managed to give it one wash before I put it on him (impatient) and it lasted 3 hours no problem with the tri fold and hourglass booster in (remember after only 1 wash, so not at full absorbancy) plus he then did a big poo . . .and it was all contained ok.
I had put a paper liner in as I suspeced he may poo and I didn't want to stain it the first time we used it! LOL! But some did go onto the hourglass and trofold boosters . . but actually it washed out no problem at all.
Reuben is in a large size itti, is 9 months old and weighs 24.5lbs. He is walking (just) and crawling . . .and it handled all the above absolutly fine (please bear in mind that I had popped out for half and hour and OH is rubbish at noticing poo . . .so he may have been crawling, walking and landing on his butt for up to half an hour with the poo in
still no leaks!
I guess it just depends on their shape etc . . . ..
luckily for us (and unluckily for our bank balance) they seem to work really really well . . .and I'll be buying lots more.
Cheeky Wipes are offering a good deal in ittis with extra boosters etc at the moment - may be investing for the new arrival too!
