I'm wondering if anyone can offer some advice. My 22mo has always been a bad sleeper, but about 6 weeks ago he started sleeping through the night and I really thought we had turned a corner finally. We all felt so much better for getting some sleep at night and he was a much happier toddler during the day too. However, 2 weeks ago he suddenly decided that he would not go in his cot and just screamed and screamed if we put him in there - I left him over an hour but I just gave up then and let him come in with us (I know - making a rod for my own back!) We've now got to the stage where we can manage to settle him in his cot at about 8pm each evening - as long as we stay in the room with him - but then he will wake up anytime between 11pm and 1am and just screams non-stop. He doesn't stop when we pick him up and the only place he is happy eventually is in our bed with us!! But even then he can take a while to settle. He's getting to the stage where he is trying to climb out of his cot if we leave him there and I really hate leaving him screaming for long periods. I really don't know what to do to try and get him to settle in his cot and room - we are all constantly so tired. I work full time plus have just found out I am pregnant again, so am totally exhausted. I feel at the end of my tether and seem to spend most nights with my head under my pillow crying! I feel completely hopeless and can't seem to see any light at the end of the tunnel. Can anyone offer any advice from their experience?
