9 month old sleeping problems

[Lily189]

Hi everyone my daughter is 9 months old and shes still waking during the night on normal night she wakes between 2 and 4 times wanting to drink some bottle on bad night it can be more if dont give her milk shell scream the house down
She has 2 naps during the day and goes to bed between 6 and 6.30
She used to stay in bed till 6 while waking up for feds 2 to 4 times now shes still waking up 2 to 4 times and now wants to get up between 4 and 5am

I've tryed keeping her up later but she just screams because shes tired
I dunno what to do where all exhausted I also have a 2year old son who sleeps from 8pm till 7am somwtimes longer
But everyone's having there sleep disturbed with her she dosnt take dummies and she has never slept through the night
I bought the Tommy tippee sleep machine that has pink light and sounds made no difference

I'm just so tired shes been an unsettled child from she was born and we found out at 3 months she has cmpa she has prescribed milk and has been great that way since but she still isnt a very settled child no matter what we do at times she will still have crying fits where she just wont stop
and now my son who's in process of being diagnosed with autism is getting really upset with her crying he now screams and throws himself when she crys and I think its because he see she gets attention from it

I just dunno what to do

All advice would be great tia

Bump

OP that sounds tough.

Have you tried any kind of sleep training?

Where does she sleep?

What time are her naps?

Is she eating 3 meals a day and milk during the daytime?

How much milk does she have during the night? As in, is she draining her bottles or is it comfort she wants?

It's awful

I've tryed letting her cry it out but it dosnt work and she shares a room with her brother
She was worse when she was in our room
She eats 3 meals a day and has her wee snacks
She only takes milk during day other than that its water when she naps she has a morning nap then goes for an afternoon one she drinks full 7oz bottle each time

At night she drains first bottle to fall asleep then drinks around another 10oz through the night

Sorry I think her wakings are normal.
My 11 month old wakes 3-4 nights for feeds.
He naps three times a day generally for 30mins each.
Around 10, 1 and 4 then bed at 8pm

Rather than cry it out maybe try controlled crying? (I know it's frowned upon on here). Let her cry for 5 mins, then go in and comfort for 2 mins, and repeat until she falls asleep. It will work but the first night or two might be tough, you have to stick it out.

Also perhaps try stopping the bottles she has during the night? She shouldn't need them if she's getting lots through the day, and a big bottle before bed. Perhaps she wants them out of habit.
