DS is 2.9 DD is D 5 months.
DD wakes a( 3am for a feed and then DS wakes anywhere between 4 and 5am and then intermittently dozes and tantrums until we allow him up at 6am.
He's tired during the day and won't nap unless we're out in the car.
I feel at the end of my tether and just don't know how to deal with it.
I've tried putting him to bed later / earlier (he's usually in bed about 7pm)
We've tried ignoring him, shutting his bedroom door, removing a teddy. We don't want to go down the root of sitting with him as that just fuels the fire.
I don't know what to try next.
