Hi, back again with the same problem. I just can't seem to help my lo sleep through

She is just over 8 months old now and can self settle but has been waking every 2 hrs through the night from midnight on and then wants to be up at 5am. I'm totally exhausted and I don't know what to do anymore.
Her routine is:
I get her up at 6am although normally awake before then.
E 7.30
S 8.30 - 10.00
E11.30
S12.45 - 2.15
E4.30
BT 6.30
I know there is 4 hrs after her last nap and I'm trying to make it later but when I have made it a bit later she will take ages to go down and then only has half an hour.
She will then wake around 9-10 pm and has a bottle, we are phasing her df out slowly, and then she wakes 12am, 2am, 4am etc. I have tried giving her a bottle. She drinks it all but still cries, I've tried water and she won't even take that she just throws the bottle away. I've checked room temp not too hot or too cold, no noises, she doesn't appear to be teething atm but sometimes I try nurofen just incase and doesn't do anything. I just don't get it. At her bedtime she will cry a little but normally only takes her about 10 minutes to go to sleep. She still has paci but can reinsert herself and a lot of the time when she wakes in the night crying she still has it in her mouth anyway.
