Rach - wow Eli is a boy on the move! I'm sure you've done all of this already like move anything that is dangerous, put up safety gates to any areas you don't want him to access etc. Bubs are a lot hardier than you think and the bumps and bruises are all part of growing up. By the time he reaches 2 there won't be a single limb that doesn't have a bruise, scratch, sore etc LOL.
re feeding - taking M into bed was a trap I got into. While it meant I could sorta sleep she was feeding all night and using me as a comforter. So I've decided that if she needs a feed I will just sit up in bed with her.
grumpiness - could he be teething? Where's the rash? My DS used to get a rash when he was teething. But best to get it all checked out JIC.

#2 tooth coming through here. Going pretty well with the routine. I won't brag about her overnight sleep last night but I am hoping that she continues it tonight. Went to an info night at her daycare and met the carers and some of the other mums and bubs. All the kids were so much bigger and more active than M. Going to try sweet potato tomorrow.
