I just started the night time cloth diapers on my son. At night the fitted diaper held up well and was super absorbent. When I took it off him it smelled bad like some strong pee. I rinsed it with my sprayer. All layers of the soakers and I put it in the wet bag. I let 2 days go by and then wash day hit. I took it out the washer and it’s the only one that smells like pee. What am I doing wrong? I use gain powder to wash them and everything else smells good.
