Hi i'm also going through a similar thing. Things i've done/going to do:
Moved all cleaning products high up so he cant reach (i have a tall cuboard)
But plug covers in spare plug sockets
Catches on cuboards
moved all ornaments to either un-reachable or put them away
catch on fridge
baby gate at bottom and top of stairs
moved all razors and tweezers and my make up on to top shelf in my bathroom cuboard (out of reach)
Moved my kettle so its now in the middle of my work surface rather than the edge so he cant tug on wires
Moved my medicines to top of cuboard in kitchen
Fire/radiator guards.
I'm also thinking of taking my coffe table upstairs as it has sharpe corners, unscrewing the glass doors on my tv stand for a little while and putting a catch on toilet (dont want him getting flushed away - lol)
I've read that most accidents happen either on stairs or in kitchen and to make these prioritory, maybe getting a playpen in the kitchen for when your cooking/washing dishes etc. Apart from what i have mentioned above i'm just going to do things as and when problems arrise.
Good luck x
