12-yo in arm cast for first time. Any hacks/suggestions you can share?

I had an arm cast 30 years ago, and this is the first time I’ve had to deal with a cast since. I remember putting a bread bag over my cast to shower. Today I saw $30 covers on Amazon. Has anyone found that to be a better choice than good ol breadbag? Are there any products out there that ARE worth it?Kiddo slept in living room in recliner for the first night, but that’s not a sustainable plan. Worst part is that his dominant hand is the one in the cast.Any kind parents out there who could offer some helpful tips to get us through the next 4-6 weeks? Thanks. via /r/Parenting https://ift.tt/2pFeeJx
