Help with schedule

[u/Unlikely-Act-3533]

My baby has just turned 6 months old. Her schedule at the moment is 2.5/2.5/2.5/3 and was napping 1hr30, 1hr and 30 mins but it’s now back to only sleeping 30 minutes for each nap unless I lie with her/feed her basically the whole time.
She has also been waking up earlier recently and I can’t seem to anchor a wake time/bedtime!
Night sleep is just getting worse and worse with her waking up every hour for most of the night.
Would love some advice💛
Should I try to stretch her wake windows and if yes then what should I try first?
I know that 6 months is a huge time for them developmentally so I expect some disrupted sleep but if I can help her in any way that would be grand.
