Early rising 22 month old

[Mazzatron]

Well here I am again...! Just wondering if anyone else has managed to help their 22 month old sleep past 4:50am?! That seems to be the magic time for us. It's getting pretty exhausting and nothing will persuade him to go back to sleep.
I'm wondering if there is something wrong with our schedule?

He wakes around 4:50 and we just have quiet time upstairs, books or just laying down in bed, I repeatedly tell him it's night time and we need to sleep. We don't go downstairs until 6ish.

Breakfast at 7.

Lunch at 11:30 and afternoon nap at 12.

He tends to nap for 1.5 hours, sometimes 2.

Dinner at 5

Bathtime @ 6:15 and in bed by 7.

He always gets a trip outside in the fresh air each day, maybe to the park, beach or walking the dog in a nature reserve. He doesn't go to nursery as my husband and I do the childcare between us. We play with him, he does painting, colouring or plays in the garden. He watches about 2 hours of TV over the course of the day generally when I need to do chores.
We don't have TV on past 5pm.

I've tried leaving him in the morning but he is stubborn and doesn't stop shouting 'Mum' for 1 hour, he doesn't give up.

He's not cold at that time, his room is 20 degrees.

Anyone got any pearls of wisdom or suggestions please?!

Thank you

Didn't want to read and run. In my experience nothing changes an early riser. My eldest was like this and still springs out of bed at 7am on the dot at 10 yes old. Was 5am for many many years. Once he reached 5 I used to allow him to go downstairs on his own to play or watch TV.

His non sleeping sister was much worse, but at 8 will now happily sleep for 10-12 hours.

Probably not the help you were looking for but once I excepted it, it got easier x

Could you try in bed by 8 instead of 7?

Bed at 8pm, and maybe consider nursery to tire him out more.

I have no words of wisdom I'm afraid, I had an early riser and tried everything but with little effect. I agree with @Wannabegreenfingers it's difficult to change an early riser. My DS is now 16 and will still be up before everyone else! The main difference between your ds and mine is that mine only had one nap and that was for about half an hour a day. Could you try cutting his nap time to see if that helps?

I feel for you. I have 2 sons, adults now. The first only had small 30 minutes sleeps during the day, never asleep before 10 and awake at 5.30 am. I never had to wake him up till his late teens. My other son would sleep all afternoon, go to bed at 8 pm and would sleep till 7 am. I would try keeping him up a little later, maybe 7.30 pm to start and see if it makes a difference.

We now have a 2 year old dog who won’t sleep past 6 am and starts barking at 5.30 am.

Oh @Mindymomo that's painful. We have a dog too and there are plenty of times he also disturbs the household sleep.
Thanks everyone. I think I do need to accept it more. I can accept 5:30 pretty well it's just this 4:45 business that's so hard! Especially this time of year.

Over the course of this week he's become super clingy, poor appetite and lots of screaming at nap time and bed time, we even co slept last night because it was the only way to stop him screaming. So I don't know if he's poorly, teething (can't see any evidence), developing or his behaviours just gone really downhill.
