1 year and 7 month

What's his routine? What time does he wake and go to bed, and how long does he nap?

He normally goes to sleep around 8 and sleeps to 6:30 or 7 and normally only has a 2 hour nap during the day 😴

The same is happening to my little guy, we cut the day nap to 1hr 30mins, which helped a little because it made him more tired but allot of it is needing connections so I have to lay with him to sleep. (Not very helpful sorry)

I have been experiencing similar. It is like mine has just realised that it's only him going to sleep and he has FOMO. mine also now seems to wake round 1:40am like clockwork and acts like he is having a night terror or experiencing growing pains/discomfort in his legs. He is not happy about being in his usual snuggle position in our rocking chair. If he falls back asleep and is put back into his cot it is only for 20min till he starts crying again. Usually after the third put down I give in and let him kick us all morning in bed and noone gets any sleep; but at least there isn't more crying.

have you considered you might be aiming for too much sleep? Babies sleep needs change regularly, you're aiming for 13 hours of total sleep on a 24 hour period which might be too much. My bub hasn't been able to sleep for that long in a day since he was about 10 months old.
I'd recommend putting him to sleep a bit later, as it sounds like he's not tired enough at bed time, and perhaps cutting the nap a bit shorter too

Thanks everyone for the information, I'll try and keep him up a little longer of a night and and cut his day nap and see how we go

I can see that he is definitely tired but he just keeps on going sometime, we will see how we go tonight with leaving him a little longer

My son is exactly the same age and for the last 3 nights has been doing similar to this. I believe there is a sleep regression around the 18 month mark (some earlier, some later). I'm hoping it will sort itself out again soon. My son's always been a fantastic sleeper - still has 2-3 hour day naps, and sleeps 10-12 hours a night. Not ready for that to change too drastically yet.

You'll have to push his bedtime back or should the day nap under 90mins. The best way to go about it is in 15min increments each day until you work out how many hours he needs in the 24hr period

Other option is to do the Mama and me resilience method by Andrea Fallon which goes into much more depth about every scenario
