Is it OK to turn a sound machine on before Shabbos and attach it to a baby stroller?
My baby sleeps with a sound machine. Is it OK to turn the sound machine on before Shabbos and attach it to his stroller? Any issue rocking the stroller and moving it around the house? Confirming it’s not muktza to move the stroller if the sound machine is on it.
It’s allowed if there is an object more valuable/important than the machine on the stroller at the onset of Shabbos. One option would be to put a sefer there.
Even if there was no object placed there, one would be permitted to move the stroller with the baby, in order to put the baby the sleep or take the baby somewhere, or even just he stroller itself if you need the place, but you wouldn’t be permitted to move the stroller in order to protect the stroller itself.
Regarding a sound machine in general on Shabbos, see here:
