My 2 month old DS leaks whenever he poops. It happens with AIOs itti bittis and BHs, also with disposables. I don't think i have had a leak with the fitteds and covers, but they don't hold as much wee and i don't have enough of them to use all the time. The leaks are usually out the legs but can be out the back as well. I am changing as soon as he poops but they just can't hold it in.

Is this just something to work around? (keep changes of clothes!) He is in smalls, i tried a medium itti bitti but that was worse.
