Night feedings how long in between?

How long does your 9 week go without eating at night?

It’s been 6 hours for mine - woke up to change her since she pees a lot at night. She went back to sleep with the pacifier so I’m not sure if I should try to feed her or wait until she’s actually hungry? It’s bothering me to not feed her but I feel like if keep waking her up she will never sleep fully through the night.

Edit to add her sleep schedule: We start winding down around 7:30 and she will usually fall asleep anywhere from 8:30-9 and sleep until 2-3 am. After that initial long sleep she’s up around 2-3 hours later but I’m on maternity leave so I get her back to sleep and we keep sleeping in until maybe 8:30-9
