I bring him in his bouncer to the bathroom with me. I’d probs be a bit paranoid as with the noise of the shower incase he started crying and I couldn’t hear.
If my baby isn’t napping in her cot when I decide to shower, I’ll put her in her high chair in the bathroom with me, with a few toys she can play with, she mostly just watches me fascinated though 😂
I leave mine in the cot as he is now crawling.
I wouldn’t recommend leaving in jumperoo. When I’m showering my Lb is in his cot - awake or asleep and my bathroom is en suite. If I use main bathroom I will pop him in Angel bath seat or laying down on floor on a towel with some toys.
I put mine in the bouncer where it’s safe and surround him with toys and books for him whilst I’m washing dishes showering etc if he isn’t napping
I leave mine in the cot with a toy, or on the play mat while I do things. Our bathroom is also next to her room, but with the white noise machine on in her room I find it covers the shower noise and she doesn't wake up
