Ugh. T used to be a reliable STTNer from an early age. Around 18 months things started to get not as consistent and by 20 months he was waking up every hour.
He goes down in his toddler bed just fine, but wakes up after a couple of hours and its downhill from there. We eventually started putting him in our bed so we could get some sleep. He'll be 2 in 2 days and it's just awful.
It's like he doesn't connect sleep cycles on his own at all now. We have to soothe him through each one, even when he's asleep in our bed. If we leave him on his own too long he'll either have a meltdown or wake himself up and be wide awake for HOURS.
Any advice? The couch is uncomfortable and so is being squeezed in a bed with a bed hogging toddler.
