Charlie used to be a great sleeper as a tiny baby, then went downhill at a few months, but for the last couple of months has been great again. But, he has now got in a really bad habit, and we're struggling to break it. When we put him to bed, he stands up!If he just laid there, he would go to sleep, but he stands up, then screams.He then goes over-tired and just won't settle.2 hours to get him sleep last night (6.30 - 8.30), then he woke up at just gone midnight and hasn't gone back bed since!Every time I put him into his cot awake, he just stood up and screamed the place down. That'll wake Stu and Kayleigh up, so I came downstairs with him and sat on the sofa till he fell sleep. After the 5th time of him waking up and screaming the minute I put him back into bed, I gave up and just sat on the sofa.He's had a couple of hours on my lap, but is now wide awake. I'm sooooo tired it's untrue. Stu's now gone work and Kayleigh's still in bed. How do I stop him standing up in his cot? Or do I just leave him to scream and hope he'll just give up and lay down?
