Do 'light sleepers' grow out of it?

[MYA2016]

DS is almost 11 months now. We always made sure even when he was newborn that we'd talk, watch telly, vacuum etc when he was asleep. Despite this he has always been a light sleeper and it's really causing problems.
It's not the loud noises that wake him, he can sleep through me whizzing food in the processor etc. But the heating coming on will wake him even though the pipes only click quietly a couple of times.
So we can't put the heating on till after his usual wake up time.
We can't use the upstairs bathroom at night at all as the light clicking on will wake him so we have to always come down even for brushing teeth.
Even us rolling over in bed will wake him if it means the bed creeks.
He started at nursery this week and they've commented that he's clearly tired but whenever he goes to sleep he wakes at any little noise such as if a child squeals.
We tried months of battling this before giving up and at home he has constant white noise on in his room which helped for months but now he almost seems immune to it again.
Where do I go from here? We have 5 family members coming to stay Xmas eve and Xmas night and I'm dreading it. I feel like I can't ban everyone from using the upstairs bathroom etc but I know he'll be awake all night.
Does anyone have any advice? If you had a light sleeper did they just outgrow it?

My friend is 62 and still a really light sleeper & gets woken up by the slightest thing, so probably not!

Ds is better now at 16 months, and once he's in bed noises tend not to wake him unless it's close to wake up time anyway.

I've got a cold and my coughing at 5.45 this morning woke him up - he's usually awake before then anyway.

Talking is one of the worst things that will wake him, however quiet.

I'd suggest that light/deep sleeping habits are ingrained and difficult to change. You can mitigate though - how about all-night white noise to drown out background noise?

My light sleeper (now aged 12) sleeps with a table fan on all night every night. It's right by her head too, on a bedside table. In winter she points it away from the bed, but it stays on.

Deep sleeping has its own problems, just so you know the grass isn't greener. My deep sleeping son will literally sleep through anything. He once slept through the burger alarm going off for 15m. However he was really hard to toilet train at night. He wet the bed on and off until aged 7 or 8. The reason was so let because of deep sleeping, needing a wee never wakes him.
