5am wake ups

[chapso]

How can I get my 20 month old to sleep later than 5am?

Nap usually around 1 - has between 1 and 2 hours. Self settles but Absolutely won't go back to sleep when he wakes.
Bedtime 7pm

Any ideas?

I'm sorry. We went through this with our first. They slept 7pm until 5am from 10 months old until 2 years old. We did it all. Earlier bedtime, later bedtime, adjusting naps etc. In the end and after months of fighting it we accepted it and I just brought her into bed with me and she sat up watching cartoons on the iPad whilst I lay down in bed with eyes closed. It's hell. She's now 5 and sleeps until 7ish.

Bring nap time earlier. I found with mine if they had a late nap I'd pay for it the next morning rather than bedtime. I would do nap time as soon as she has had her lunch. Lunch could be at 11:30am. Nap time 12. If that foesnt work then cut nap down to 1 hour. If that doesn't work then last resort put to bed at 8pm aswell as the earlier and shorter nap time.
