Any help for a tired mama? (Long post, Im sorry)

So I’m going to sound awful saying this,

Our little guy is 7 months and 3 weeks old. He’s an awful sleeper, still wakes at least 5 or 6 times a night, and sometimes it can be as many as 15, but I can lose count.

He’s still in a crib next to our bed, the type that goes side down next to us. Hes been crawling everywhere for a month or so now, and last night i caught him trying to crawl out of his crib and into our bed when we were out of the room. (despite having a sleeping bag on!)

We are in a small two bedroom flat with our 9 year old daughter, obviously he’s needing a big boy cot and his own room, we should have moved to our new house, but because of covid restrictions, the sale fell through and now we are back in square one. We have no room for a cot in our bedroom.

Tonight, we tried putting the side up on the crib but he screamed for nearly two hours before eventually falling asleep in my arms and me placing him down carefully. I’m at my wits end, I don’t know where he’s going to sleep when we can’t get away with the crib and I’m just so goddamn tired. My husband is fantastic support but it’s really wearing us down.

He’s suggested we move our bed into the living-room and give up our bedroom until we can sell the flat, but I can’t help but think perspective buyers will see us all crammed in like sardines and think the place is small and lacking space.
