my son is nearly 19 months old, i have allways been lucky with his sleeping pattern. he allways used to sleep from 7pm-8.30am. he sleeps in a cotbed, but in the last couple of weeks we've changed it from cot to bed, the first couple of nights were fine but now it's taking at least 45mins to get him to bed as he keeps getting out, he is also waking at 5.30am with no joy of him going back to sleep. what can i do??? please please help me
