My first son was really easy and my second had about four months of really bad crying fits I was so thankful I learned the walk away and decompress for five minutes with my first. A five minute break could hold my sanity for another thirty minute wailing session. I think I would have gone insane otherwise. But yeah, their needs are incredibly easy to identify and work through just like you said. It’s just exhausting. A couple times were pretty scary because I woke up in a jolt with that feeling like I was going to drop something. At some point I sat down in a rocking chair and fell asleep while holding our second without having any memory of doing so. After the second time I asked that we be able to remove the rocking chair from the bedroom because I obviously didn’t have the foresight to not sit down while holding him in whatever my mental cognition was during that period of time.
