You can do it. Admittedly I had help, but there's a few things you can do in preparation. Off the top of my head:
Make sure everything is in non-bending reach, e.g I put one of those hanging basket things in the shower so I didn't have to bend down for shampoo etc.
Change baby at waist height e.g on your bed or a changing table, rather than on the floor.
Loads of pre-cooked meals or easy things in the freezer.
A cleaner, if you can afford it, even if only for a few weeks. If not, no worries, the house won't fall down if it's not cleaned.
Each morning put on the sofa a bottle of water, snacks, remotes, book/kindle, laptop, phone, whatever you'll need for the inevitable hours on the sofa.
Good luck! The pain goes away eventually and you'll move easily, even if it doesn't feel like it at the start.
