5 months - sleep without feed

How long would you let your baby sleep at night without feeding?

My almost 5 month old (born 8 weeks early) will happily be fed at midnight, then go to sleep until around 8am, sometimes 9am and usually we have to wake her for her morning milk (formula),

I’ve read lots of different opinions of how long a baby this age can sleep without waking for milk, can I hear some of your thoughts please?

My baby still gets her full amount for the day and has a feed every 3-4 hours throughout the day.

She has caught up really well with weight, going from 0.14th centile at 1 month old to 47th centile last month
