A swing. I have seen it work many times.
Like a hammock sort of thing. I used to work with Native people (Indians) in Canada and they always strung up a hammock-like thing in the house and would swing an unhappy baby in it and the baby would always quiet right down.
Of course they lived in log houses and would screw in eye-bolts into the logs to hold the hammock ropes. Across a corner. You can manage something, I am sure.
It really works. You have to stand there and push it but it’s better than the screaming.
The harder you swing it the better they like it. I’ve seen adults sitting at a kitchen table playing cards and they would deal a hand, reach up and swing the baby, look at their hand, swing the baby...
I have seen pictures of suspended cradles in Afghanistan, same thing.
Probably invented for screaming babies about 12,000 B.C.
It’s sure worth a try.
My son screamed too. A wind-up swing was a huge blessing for him. Car rides helped enormously too; I took him with me for every errand. I continued to breast-feed him, and not on a schedule either; sometimes the breast milk is digested very fast and the baby is hungry an hour and a half later. He was screaming for a legitimate reason. When we started introducing solid food that cut down on some of the screaming too.
I had to continue to exclude caffeine from my diet.
Careful not to get too vigorous with swinging and cuddling. Sometimes people think that if a little swinging is good more is better, and they chuck the baby around so strongly that the baby can risk Shaken Baby Syndrome.
