How to teach a 1 year old to self-soothe during the night?

without leaving her to cry probably not, which is not good for them, its just children seeking comfort from their parents, i know its hard waking up in the night but it wont last forever x

You can try enhancing the before bed 1-1 connection time with each parent and using a comfort object to help with the separation of night time, but it’s pretty normal at this age

How does she go down? Do you have to Pat or cuddle? You could try replacing the sleep association for falling asleep and then being consistent with it in the night once she’s used to it.
For example, if you stay by her side but only sing lullabies to her rather than pat and cuddle. She will be upset at the change but at least you will be there and she will know that. It depends what you’re comfortable with in terms of sleep association and crying.

Also, just to mention, do you leave her a few mins before going in? Only because my boy would stir and we would rush in and realised actually sometimes he will go back down on his own within a few mins. All babies are different but I hope you find something that works for you guys

She's still sleeping in our bedroom at the moment, so there will always be someone there to comfort her. If she doesn't get pat in time she will be fully awake then cry really badly

There is a 12 month sleep regression. Depending where she's at with teething, she may also be cutting molars which really hurt and take forever, like 3 months.

Do you play white noise while she sleeps?

Sleep training. I get shit for it but I just don’t believe that waking up every hour for a year or more is appropriate or sustainable even if it “won’t last forever”. By that age they are able to learn to self soothe. Some kids never need sleep training but some do and that doesn’t make anyone a bad parent
