My 4 month old exclusively BF boy at a few days past 4 months went from sleeping 8-9 with one feed around 4, and a few dummy replacements to literally overnight not going down. He used to wake and usually be able to settle himself back to sleep 80% of the time. We co slept for the first month and then he moved into the beside me crib with minimal issues.
As of the last 3 nights he is now waking up literally every 20 minutes, sometimes less. And waking up screaming and inconsolable. On occasion he’s made himself sick through the crying. Cuddling him doesn’t work straight away, bringing him into our bed makes no difference. He’s had calpol on 2 of the 3 nights and that’s made no difference.
Dad currently has him out walking around the house and he’s still crying. we’ve tried driving him in the car, the pram etc.
Is this a normal sleep regression or should I be concerned?
