Question:
My son is almost bar mitzva and he still wets the bed. Is there a problem if he wears a pullup on shabbos? The sechita aspect and the fact that the design disappears when it gets wet?
Answer:
Hello,
It is permitted for him to wear them. Obviously, he should be careful not to squeeze the pull up, but this is not different than any parent changing a child’s wet diaper, that it is permitted, and they should be careful not to squeeze it.
Regarding the design that will disappear, that is also permitted, for a combination of a number of reasons. First of all, the is no benefit to the diaper gain by the design disappearing, therefore it is not mochaik, that is considered positive, and it remains d’rabonon. Added to this, the child has no intention to erase the design, and it is aino miskaven. Additionally, it is not a psik reisha, because the child might, not make the diaper wet, before it is changed. Additionally, it is only a grama, which will also lower the action to a d’rabonon. Due to the combination of all of these reasons there is no concern here of mochek.
Best wishes
