Uhhhh

Jerk your buddy off for him since he can't do that right now

Cleaning service, any house services really, freezer meals, or other little to no prep foods, offer to play with their kid from time to time, help them relieve stress by unburdening them (by taking on chores), instead of providing an escape (video games)

Edit: not dissing video games, but a young one and another on the way is a lot of stress already.

Thankfully you're not his mom.

I've broken a lot of bones.

Get him stuff that helps the family so he doesn't feel useless and guilty. That's number 1. It's awful to feel like a burden to everyone, and that doesn't go away no matter what is said to you.

Second, stretch bands to put around limbs and pull. It feels amazing. You don't realise how little you move and how little muscle you use while subconsciously "nursing" a broken bone.

Something insanely complex that involves both arms to use or solve. It's just funny as shit. But also, I swear I recover faster.

i would get him a cheap violin and a bag of individually wrapped candy

You don't give your friend a thing, you give his poor wife something. A bidet goes so long and pregnancy itself is hard.

Seriously: Offer her to do some chores like shopping, gift them some take-away gift cards,etc. The situation will put a serious strain on their relationship,

Gag gift. Since he broke both arms, and wrists, he hopefully can still hold something lightweight.

In all seriousness, if you want to be helpful the best thing you can do is spend some time with him in person. He can tell you what he needs, and you can show him you care. If I got seriously crippled like this I probably would start thinking that none of my friends will make time for me because I have become a burden. Prove that nasty self-talk wrong!

Firstly, my sympathies for your friend's horrible situation

Secondly, don't let him near anyone's mother.

Me who is 51, active boarder (skate, snow, surf, downhill) since the mid eighties, and has never broken a bone, reading this:

I miss r/neverbrokeabone

Oh no.

Can I ask how that happened?

I think what he and his family needs is help with chores. How well you can help with that depends on how far away you are.

I'd say audio books, but you can get them the Libby app and a library card and they'll have tens of thousands available for free.

So depending on how much hand dexterity he has left with the broken wrists I suggest a back scratcher and one of those reacher grabber arms.

A glass of milk. Might get that 3 months down to 2 months and 29 days.
