You mentioned a toddler at home. That's going to be a challenge all right, and I can definitely see why your doctor might prescribe additional help. When I had a bad sprain last year mine didn't, and we really struggled without it for the first couple weeks. And my two were still babies at that point, not walking everywhere and having to be chased after! I can really sympathize with your predicament.
Call SUVA - "I've been in an accident," (be prepared to give the case number from the accident form), "and the doctor has prescribed X amount of household and childcare help for X weeks. Can you please help me understand how much of this the accident insurance will cover?"
Unfortunately the answer is probably going to be "none of it." Normally they cover the medical side of home care (changing bandages on a wound etc) but do not cover the household help side, even when these are provided during the same visit by the same person.
Do you have any supplementary health insurance? Might be worth reading through the policy on that and/or giving them a call.
A few ideas for managing without the extra help, if that turns out to be necessary:
Note: I don't know how big your kid is ("toddler" covers such a dramatic range of abilities) nor whether you have a boy or girl - so apologies if either the gender or the advice is off...
- YMMV but I found crutches to be totally impractical inside the house. There's never anywhere to park them that they won't fall over, or that the kids won't come and take them away to play with. So my crutches lived downstairs by the front door and I crawled up the stairs and then crawled or knee-shuffled my way around the house like some creature out of a horror film. But hey, it worked.
- You mentioned you work, so I'm assuming he is in daycare at least part of the week. Your big problem on those days - apart from getting to work yourself! - is going to be pickup and dropoff. The daycare can certainly help with the physical side of that, wrestling him into his coat and shoes... do you know any of the other moms well enough to ask for help getting to/from the bus stop? Especially if he is on foot, someone to hold his hand while crossing the road is bound to be a big help.
- How old is he? Out of the stroller already? Even if so: it won't hurt him to hop back in it again for a few weeks. I found using our jogging stroller as a granny-walker was a lot easier than walking on crutches - plus no danger of having to chase down a runaway. Of course the flip side is that getting it on and off public transport can be a nightmare, and even at home you have to have somewhere at ground level to park the thing...
- ... which is why you need to contact your neighbors. Explain that you have had an accident, are on crutches for the next 3-6 weeks (or whatever range the doctor anticipates), and so you will have to leave your stroller parked just inside the front door (or locked to the bike rack, or wherever is a convenient place in/around your building) since it's impossible right now to fold it and put it away in the cellar. You wish to thank everyone for their understanding and really hope that it will be for 3 weeks rather than the full 6. (As a side benefit this alerts the neighbors that you are struggling... you may be surprised how many step forward to offer help of one kind or another, once they are aware of the situation.)
- On weekends, and any other days you are at home with him, the biggest problem is going to be exercise. Get someone - a neighbor, another mom from the village playgroup, even hire a babysitter if you need to - but get SOMEONE to take him to the playground, ideally at least once a day, and really tire him out. Even if you have to tag along too (separation anxiety or whatever) you can just sit on a bench and let someone else be the one to chase after him, and he will get way more exercise than staying at home with you. More exercise means better meals, better sleep, and (in my experience so far) also fewer tantrums.
- Are there stairs in your building? Is he comfortable going up and down them safely? If not, you can use a baby carrier... you can strap him onto either your chest or back while sitting down on the sofa, and then crawl or crabwalk your way down the stairs with him attached. Alternatively if you feel he is ready, you can embrace this as the right moment for him to learn how to do stairs: you sit at the bottom of the uppermost flight of stairs (this way he can't go any higher or any lower, and you have a decent chance to catch him if he falls), and just let him practice going up and down, up and down, till he gets the hang of it.
- Other miscellaneous day-to-day logistics: if you usually lift him into his high chair, try parking an adult chair or even a little stepladder next to it and letting him climb up. Same goes for lifting him into his bed, if he still has the kind with sides. Buy some disposable changing mats and then you can change diapers (again, if he still wears them) on the floor or sofa, no need to lift him up to a changing table.
Sorry for the huge wall of text
I hope some of it helps you, and I hope even more that insurance miraculously agrees to cover everything and so none of it's necessary!
