@bobezeh It probably isn’t helpful but here’s what happened for us:
We had 90 - 120 min increments for months. We dealt with several food allergies or irritants/intoletances (dairy, soy, corn, oats, legumes). I posted at 4 1/2 months and a lot of people said that there was definitely another issue and not to sleep train. They were right.
Around 7 months we realized the more donor milk we gave, in place of my ‘paleo milk’ the worse our baby would sleep. We would do shifts and I would get up and pump (I still do) as well as stay up late to pump. I was exhausted. (Still am somehow, but different now)
Turns out my baby is allergic or sensitive to corn and the more that was in her system the worse off she was for sleep.
Once we figured that out we got a lot of 4 hour stretches and now at 10 months we have 0-3 wake ups a night, but usually 1.
Is it possible that your LO is suffering with a food sensitivity that’s affecting sleep?
FWIW: my terrible parenting moment: I had a night out and was pretty buzzed, I was NOT getting up. My husband would not get up so we let LO cry it out for an hour… on and off, she was not bawling the entire time. She did learn to cry herself to sleep that night though. Which was good for awhile until we hit another allergy
