Never had probs before.Ds keeps getting out of bed as soon as I shut the door.He opens the door to come out.The first few times I say nicely Its time for bed to sleep,I then say nothing and put him straight back to his bed,he laughs and runs to is bed beofre I get to hime sometimes.Last night I could not take anymoe so put him in the travel cot!! He cried horribly but went off to sleep.He then woke at 4am screamed for an hour befoe I gave in and he came in to my bed.I was so tired.Whats the best thing to do?Is he trying it on or what?Just about to put him to bed now!
