I’m from Jamaica, my son is 7 months and at nights I honestly co sleep with him plus I would give him cornmeal porridge like 5 pm . I made the porridge thin but it fills him up and he only wakes up 1 or 2 times to breast feed in the night.
Sounds like it could be a late 4 month sleep regression. Just have to ride it out mama it will end x
Maybe sleep regression or you can also check his gums if you see them inflamed or a little bit of white underneath maybe it’s that and you can numb it with a wet cold cloth or try a cold meal before he goes to sleep… good luck
My baby wakes up every hour if I’m not sleeping with him at 5 month old it rlly is rough out here
