@Scuba Gal. Has he started crawling yet? I going my two had scrappy sleep when they were learning to crawl and once they worked that out they slept fabulously as they exhausted themselves out.
The other suggestion is to feed them to sleep lying down and then leave them on a mattress on the floor.
Or the pram. I used to occ walk both girls to sleep.in the pram and just park it in the house. Or if bad weather just push the pram over a coat hanger in the hallway.
Hugs. Been there. It's tough but you are doing great. Babies pick up on your angst so if you are both getting frustrated then call it quits and go chill and watch a movie.
