I set up a clock in Jakes room to go off on white noise at 5am coz thats when he started to go into a lighter sleep, and left books at the end of his bed. We went from hearing him yell straight away to not hearing him til 7.30-8! I was a very happy mummy lol I would suggest keeping your boy awake til 6.30 which is a reasonable time. Jakes in bed by 6.15 and asleep by 7pm at the latest usually and I don't get him up again til 7.30am. Maybe get some earplugs? If you ignore him til you're ready to get up he'll soon get the picture (Jake did

).
As for the day sleep - at 17 months Jake was having 2x2-3hour sleeps and still sleeping a minimum of 11 hours at night. It totally depends on your child as to how much sleep they need. Some just need alot more than others!
