My 12 week old is EBF and wakes up every 2-3 hours to feed at night. It seems like most babies are sleeping for much longer stretches by now. I don't know how to encourage her to sleep longer!

She falls asleep without too much trouble and her bedtime is at 7:30-8pm. We've tried dreamfeeding and it didn't make a difference. Recently I tried to pat her bum to get her to sleep a little longer and it works 25% of the time. Her naps are good (I would be a zombie without them!!) and she has 2-3 naps that are 1-1.5 hour long usually.

When did your EBF babies start sleeping longer stretches?
What is their bedtime?
Any advice on what to do when they wake up in the middle of the night?
