Just turned 1 with messed up pattern

[Stephaneey]

Hi
just posting as had a couple of bad nights and don’t know where to turn. My DD has never been a great sleeper (she actually slept through from 5-6 months but only a couple of times since then).
She seems to stay awake for absolutely huge chunks of time so now I think she won’t actually be tired at all at night.
Yesterday was a bad example but she woke up at 10 (late I know)
She then had a nap from 15.30 to around 4 (fell asleep in the car then woke up when we got back home)
Finally went to sleep at about quarter to 12.
(actually scared to admit to that)
The night before she went to bed about 8 but kept stirring every so often so I co slept from around 00.30.
I’ve realised if I don’t feed her to sleep it is a huge battle to get her to sleep. I don’t actually know how I can do it.
Could it be the switch to cows milk? She does seem gassy after her bottle, I’ve been giving her half cows milk and half formula.
The early nights are always when I’ve fed her to sleep (bottle) but if I don’t do this (she doesn’t fall asleep or I get the timings wrong), like last night she stayed up an extra 3 hours after her evening bottle. Any advice?

Why are you allowing her to wake at 10?

Wake her at the time you want her routine to start and go from there. So if you want her to wake at 7am, wake her then regardless of how well she has slept the night before or what time she went to sleep.

Then following wake windows do her first nap 3.25 - 4 hours after, so in this example that could be 10.15 - 11.15 and the second nap the same amount of time so 2.30 - 3.30 and bedtime at say 7pm.

If she has a poor night or doesn’t fall asleep until late, still wake her at 7am to set her natural rhythm. Nothing wrong with feeding her to sleep. She isn’t sleeping properly because you haven’t created a routine - it’s too adhoc.

Yep I’ve never had a fixed bedtime, I do try to do the same things when I think she might be ready for bed but just recently I’ve found she can stay up for hours after my routine. She did usually have a bedtime from 7 to 9 depending on her naps but that’s just gone out of the window recently.
I used to try to look at wake windows but I’ve never been sure how to get her to sleep if she doesn’t want to, I don’t actually know how people do that lol.

That’s the problem though. Children thrive on routine.

She isn’t going to go to sleep at a reasonable time or sleep properly in the night if you’ve allowed her to wake up whatever time she wants and nap whenever she wants.

You need a reset.
