15 month old has always been a pretty good sleeper, 7.30-6.30/6 everyday for a long time. For the past 2 months, very different story. He goes to bed at 7.30, wakes up at 2.30, 4.30, 5.30 and then that's it. He stands up in his cot and screams, not cries, screams, like a shrill throaty scream. He screams so hard he ends up sounding like he's lost his voice. It's so upsetting. He cut all his first molars around the same time this started 2 months ago, so we assumed things would settle down but they are now fully through and all other signs of teething have stopped and he's still doing it. Sometimes if we leave him to cry for 10 mins he'll fall back asleep but sometimes nope. I've been up with him since 2.30 and everytime I calm him down he starts screaming the second I put him down.
We've always made sure he self settled, we put him down at night and for his naps awake. He is fine at those times.
He has a nap at around 9.30 for 1.5/2 hours.
Sometimes he has a mini nap at 4-4.45 but not always.
We've tried pushing bed time earlier, later, we've tried letting him nap in the afternoon, keeping him awake. I'm at my wits end.
DH has now got in the habit of bringing him into the spare room and sleeping in bed with him this last week just so we can all get some sleep but I just know deep down it's making it worse.
Please can anybody offer any advice I really can't keep doing this forever
