Bedtime for 5.5 month old?

What time are you putting your little ones to bed? We’re having some trouble with nighttime sleep. We were going to bed at 7, wake up once to feed, then sleep until 7. Now we’re still going to bed at 7, waking up 2 to 3 times, and then getting up at 6, sometimes 5am. We’re struggling to stay up until 7 and most often nights falling asleep during our last feed.

I’m thinking about moving his bed time up to 6pm? Thoughts?

Btw, he is EBF, so I don’t really expect to eliminate night feeds completely.
