My first born (now a Marine) would not sleep unless he was, somehow, in motion. Ride in the car? He slept peacefully, but transfer him into the house and he would wake up immediately.
I would ride the lawn mower with him in my arms so he would sleep. We would put him on the washer or dryer when we did laundry for his siesta. We finally got a vibrating swing chair for him. My wife and I referred to it as, "the neglectomatic".
LOL! My #4, one of the spewing babies, is a Marine.
Two of my cousins were fussy babies. Nothing worked except “ride in the car.” Even at 3am, Auntie would take them for a spin, then carry them back in the house like she was carrying explosives.
Luckily most babies settle for a walk in the nursery.
