DS (2.3) has never been a great sleeper but things are particularly bad at the moment. He's in a proper bed with bed rail with a stair gate across the bedroom door.
The thing is most advice I come across seems to concentrate on getting them to sleep in the first place. This is not a problem. He has a bedtime routine ending at 7pm when he will generally stay in bed and go to sleep no problem. Then anytime from 12am he'll wake up, get out of bed and come to the stair gate to shout for us. When one of us goes to put him back to bed he'll just go straight back to sleep...until the next time. This can be 20 minutes later and last night went on about every 10-20mins for several hours.
We have a Gro-clock which worked brilliantly whilst he was still in a cot, but now he's in the bed he doesn't seem to look at it. He still has a nap in the day, after lunch, but on occasions where he's missed his nap he's slept no better for it at night, just been grumpier in the evenings.
Because our eldest has GCSEs starting soon and the youngest is only 12 weeks old we tend to jump up at the first bellow to minimise disruption to them. Any suggestions gratefully received!
