I would only have one out at a time, among a few toys that aren't noisy. Then rotate after a few days.
I let my little girl pick one out of the toy box a day the non noisey ones stay out at the toy bins . She enjoys this and it helps me keep sane as I also have 2.5 year old who would also turn them on and just walk away.
Rotate and earphones. Try rotating 2 and if not just have 1. As long as y’all are content, it’ll work out. Earphones help me drain other noises out some and it helps.
definitely a toy rotation. i can’t stand having more than 1 noisy toy going at the same time, luckily my daughter only has a few lol
Absolutely rotate them!
