Leap 6 / illness - 8 month old waking all night

[Lgw20]

So my DS has got a snotty nose and has been waking ALL NIGHT LONG for about 4 days.

Usually a cold only affects him for 1-2 nights max.

Basically he self settles for all naps and sleep at bedtime just fine. But wakes an hour after bedtime screaming and will either be wide awake or only sleep on me.

I thought it was his illness but now I'm thinking it's some sort of regression / Leap 6 thing because I put him back down and he screams. Repeat until I got crazy 🙃

If I get him to sleep on me eventually... we will put in the cot and he will wake 30mins later.

He used to go down between 6-7pm and sleep through till 6am with one feed.

Do you think this sounds like an illness or regression thing? Any tips!!

I could have written this. There is an 8 month sleep regression which I think ties up with leap 6.
My LG has a cold too and she's been so snotty at night. I think we are coming out the other side now. It's been 3/4 weeks of bad sleep.

My just turned 8 month old is exactly the same. We’d started some gentle sleep training (stopped feeding to sleep, replaced with sshh / patting with a view to do a gradual retreat) but that’s all gone wrong over the last few days - hysterical crying unless I feed him every time he wakes. He’s also rolling and crawling in his cot, getting wedged sideways! Desperate to try to continue with the gradual retreat as it worked wonders with my older child but don’t see how I can possibly start when it seems we’re in a constant cycle of illness and developmental regression
