Formula may be more filling, but breast milk contains the sleep hormone melatonin.

My baby’s sleep improved when she started on solids.

Definitely, formula usually means bub’s tummy will be full and that will help them sleep for longer

You can mix formula to different thicknesses, so yes I have been told formula us more filling and keeps them satisfied for longer

Short answer yes. But this doesn’t mean you have to be up all night, avoid snack feeds & give final feed as late as possible. I had to go into my room for this one at first, somewhere totally quiet so bub got a long uninterrupted feed & plenty of hind milk & gave him a little poke when he was dozing off & he’s fine till 6 or 7 am good luck either way!

A lot of people suggest formula for night but does your bub already take a bottle? Also if formula doesn’t agree with bub you could find yourself with other problems like reflux and constipation. I would keep breastfeeding as whenever I’ve tried formula at night one of the above has happened.

All I can say is yes from my own experience. My one son used to keep me up almost all night as he would suck for a couple of mins then sleep only to wake up again to suck. It was so tiring. Eventually feeling like a zombie, I started giving him formula at night. What bliss! He would sleep 3 to 5 hours and when he went onto solids, it went to 7/8 hours. I was one happy mum.
