Diaper blowouts while in jumper


My son is a little over 4 months and obsessed with his Fisher Price jumperoo. It seems like every time I put him in there he poops, though! Since his crotch puts weight on the seat, it seems to always get pushed up out of the back of his diaper and it makes a huge mess. We don’t have issues with blowouts unless he’s in the jumperoo because his diapers usually contain his poop really well. We use Pampers Swaddlers during the day when this happens. Do you think it would make a difference if I tried other diapers, or is this just something we have to live with? Also, we tried Huggies when he was a newborn and they gave him a rash that seemed to be an allergic reaction.
