my 30 week boy used to sleep very well at night (up until about 3 weeks ago) but his day time sleep has always been variable. We sleep trained him quite young and has no difficulties going to sleep but he keeps waking up. the more his night time sleep is disturbed by him waking (we don't have to go in) the more overtired he becomes and there is a vicious circle begining to emerge. He is becoming increasingly unhappy and I am worried that his sleep deprivation is causing him harm. He naps at about 9am for anything between 30mins and an hour and then again after lunch between 12.15 and 12.30 if he wakes up after 3omins that is the nap over. I can leave him in his cot for well over 2hours he won't cry but he won't sleep either. I have read healthy sleep habits, happy child, gina ford, tracy hogg and every other book under the sun please is there anyone out there who has the same problem or who can offer any enlightenment. i am desperate
