Hi Op,
I broke my ankle a couple of years ago, similar to you and had it all pinned etc.
My dh had to fly out for a week 3 days after I got back from hospital, and my mum also had to go away 2 days after that. I had 3 small kids, youngest was 3 and it was a nightmare!
Ok, for when you get home.
The first few days are pretty rough, like being hit with a sledge hammer. Get anyone to take your baby who can, if necessary, get someone in to watch/play at your house so you can stay on sofa. Get dh to set you up a corner with snacks, bottles of drink, buy a thermos for tea/coffee, and books. And pain relief. But for those 2-3 days I slept loads.
Getting roudn on crutches is really hard to start as your foot hurts and you feel lousy. Top tip, get an apron with a pocket and wear it, as you can't carry anything when on crutches and you can put mug and thermos in an apron pocket.
After the first week everything get sa lot better. I had an open cast for 2 weeks, until the surgery woudn was healed and swelling down, and then a proper cast. Once the proper cast was on, everything was so much better, easy to move round, less painful to move round and easy to sleep etc.
If you can get throuhg those first 2 weeks, it will all start to improve.
Warning though, I had my cast off at 6 weeks and went into a boot, it then took another month before I was off crutches and just in boot, and then suddenly it felt OK, strong and heale dand 'safe' to walk on and I could get rid of the boot.
I had the most amazing friend who came round and cleaned my house every week for me. I hardly new her at the time, and it wasn't easy to accept such help, but it was the key that mad eour friendship and now she is one of my closest friends.
