How long does your 5-6 month old sleep for?

What time is bed time? What time do they wake up? Do they sleep the whole night through or wake up for feedings?

We put our baby down for bed at 9:30-10 and no matter what we do she always wakes up at 12:30 thinking it’s play time. She’s been fed and changed. Just seeing if other mamas have a baby that doesn’t sleep through the whole night and what I can do
