DS2 has , until now, been a pretty good sleeper. We could put him down sleepy but awake after a feed and he would suck his thumb until he fell asleep. Hooray, we thought. We were due a good sleeper we thought as we've had real issues with DS1 (2.8yo) having sleep apnoea and waking screaming, terrified many times a night.
Now, DS2 has bath and feed but screams blue murder when we put him down, and keeps screaming until he gets fed to sleep, which is not what I wanted to wind up doing. He's also waking every 1.5-2 hours (previously slept in 4 hour stints between feeds), screaming until fed to sleep again. We are now co-sleeping for this reason.
I don't know how to tackle this. Just persevere and hope its a phase/growth spurt/development leap/teething issue, or try and deal with it somehow. Frankly the lack of sleep is making us ill. DS1 had his tonsils out recently to stop the apnoea. His breathing is great but sleep is still really crappy - needs hand holding still to go to sleep and has regular night wakings. We can't let DS2 just scream as it's waking DS1.
I should change my thread title really - how can we get both our kids sleeping better? And how do people do sleep training type stuff when the screaming wakes other DC?
