Sleep deprivation sucks!

We have an open door policy I dont think its good for a baby to be locked in thier room but if you feel its right for you then do it. It must be scry having a door closed on you when you dont quite understand especially if he is struggling with bedtime already? Maybe leave it ajar with a hall light on so he knows where to go?
Is he going through a major change, learning something new, having a growth spurt? Have you thought about maybe bringing his bed into your room and slowly getting him to sleep in the bed all night then moving it into his room? What about starting him in your bed then moving him?
My DS1 has started sleeping in our bed again...some nights he will sleep in his bed...but we make sure he is always welcome into our bed cause I dont want him to be affraid of sleep

Good luck hun I hope you work something outx
