My little one turns 3 in a couple of months. Never been a good sleeper - never slept longer that 20 mins before 4 months (CMPA), never more than 2 hours after that (eventually found to have severe obstructive sleep apnea). Since tonsils and adenoids removed earlier in the year slept much better - down to 3ish wakes a night. Usually calm when they wake and easily settled.
But for some god forsaken reason the past 4 nights in a row they have woken up every single 20 minutes screaming. When I say screaming I mean blue murder. Nothing calms them, they scream for 30+ minutes every single time. We ask if they're in pain, hungry, thristy, hot, cold. Always says no. We ask them what's wrong, all they say is they're tired. But they're the one waking up the neighbours screaming blue murder 10+ times a night! They're absolutely inconsolable and we can find no reason for it. All that helps is putting YouTube on some bedtime stories until they go to sleep again but not really sustainable.
We're completely wrecked and neighbours are complaining on both sides. Anyone have any ideas?
