Hello! I’m desperate for some advice 😞

So my baby girl is 10 months old, she never sleeps.

She naps twice a day (very short naps), we start our bed time routine at 7:30 pm, then she wakes up after 2 hours or less 🤦🏻‍♀️ and she’s wide awake 😞 i try my best to put her to sleep which takes A LOT OF TIME , until she gives up and sleeps at 12 am or so.

AND at night time she keeps waking up and doesn’t go back to sleep unless i nurse her ( she was exclusively breastfed and only sleeps while nursing).

I don’t know what to do i’m so tired, any advice?
