How well does your child sleep?

The brat has always been a light sleeper, plus he has always had an adenoid issue. In fact during some really bad attacks, the combined snoring of the brat and the husband is enough to rattle window panes. Of course I am being modest and not included mine own decibels into this equation but then I'm not the one who hears me snore.
Plus there is always so much more to do with oneself that lie down and go to sleep, so we have had instances when the lights are switched off, Pappa Bear and Mamma Bear haul their lard into the bed, the blankets pulled over them and gentle snores emanating from both while Baby Bear continues to dash his cars in mock races in the vicinity of their feet. Sadly, the commercial call centre building just opposite ours ensures that even with the curtains closed and the lights off, there is enough light to have a mock F1 championship on the bedspread with Mamma and Pappa being the uphill terrain.
Finally, Pappa will start up with a fright as one errant driver skids and crash lands into his nostril and bark the brat into sleeping. And the brat will lie down reluctantly, toss and turn, mutter dark things, insist on hand under head, dispose of hand under head, want to be held, decide he doesnt want to be held, toss and turn and finally, Mamma drops of to sleep muttering dark things and has no clue as to when the brat if ever, drops off.
And yes, he is the acknowledged runt of his class. Which is why this article scared the night pants off me. Yes he does sleep less than he requires. On a very good day he sleeps at 10.30 pm and needs to be up by 7.30 am to leave for school by 8 am. It helps that school is a minute away. We're normally the ones scampering in as the bell rings every single day.
On some days he will sleep in the afternoon for a good three to four hours. I let him sleep in, despite the fact that he will oversleep playing time, because he does get such little of good deep sleep that any sleep is good for him.
His sleeping habits are a bit better now. He sleeps. There were phases when I have sat up all night with my eyes like saucers following the brat bouncing off the walls on hyperoverdrive, with him just refusing to go to sleep.
And he does have a wind down routine. Come up from play, do his homework and leedle padhai. Eat his food. Play rough tumble with the pater. Drink his milk and lights off. Sometimes, if mamma's eyes are open, she will read him a story which he will punctuate with inane questions which all lead back inexonerably to Batman, Superman, Spiderman and Krishman. Yup. The latest is Krishman. At which point Mamma will give up and combine Grimms Fairy Tales and Marvel comic characters into a mish mash of plots that holds the attention till the small yawns start. From Mamma. The brat is still google eyed. And for all ye thinking sugar overdose, no, he has no chocolates and no sweet and no colas and no Lays or junk food. Only two spoons of sugar day in his two cups of milk.
Any words of wisdom to get this child to sleep better? Mamma's tired of being Mrs Raccoon. And she would so like to see the brat not being the current 'Chottu' of the bunch.
