18 month old, the right amount of sleep

[thinkalot]

my son is a very active and advance 18 month old, we had struggled with split nights from six months old. At 15 months I got in touch with a sleep Consultant for some guidance.
the split nights had mostly stoped (one a week) and he sleeps through the night with her advice to minimise his sleep.
Her original advice was 7am wake up, no matter how the night was, 1.5 hour nap at mid day and 8pm bed. To move milk association away from sleep (I think was the real game changer)
However that didn’t work and we had to cut to 1hr nap and bedtime has crept from 8:30pm to 9pm.
i have tried for a few night to move bedtime earlier but he alway full asleep around 9pm. He had never done will with a early bed time.
I’m still waking him around 7am

Now my concern is if he’s getting enough sleep enough sleep?

I would love for him to get another hour or so but with out it making bedtime later or of course impacting the night.

You can't make them sleep more than they need and sleep needs are so individualized. Average total sleep in 24hrs for his age is 11-14. He was doing 12.5 it seems and he's now doing 11. So although it's lower needs it's just about within average. You could try an earlier wake and shifting everything else earlier maybe? Is he happy when waking?

Hey, thanks for your reply.
He not up set when I wake him, he just take a bit of time to come round especially from the nap, that one of the reasons I wonder if you could do it a little bit more sleep
I go through waves of insomnia my self so I don’t wake to wake him early then 7am. 😩

I'd drop the nap. My son napped until he was 3.5, my daughter dropped all naps by 18 months. Slept much better after doing so. Some just need less sleep.

I going to play around with times a bit and see, I hate feeling like him I’m messing with he’s sleep.
Yesterday I wake him up at 7:20am, he had a hour nap, went to sleep 9:10ish and didn’t wake up to to 7:10am naturally. I happy with that as he wake on he’s own :)
