I'm only formula feeding my kiddo who's now almost 6 weeks old. I was told by midwives that he needs to be fed every 3 hours, even if he's asleep, but can now push it to 4 hours at night (which we do sometimes if he doesn't wake up beforehand). He takes roughly 100-150ml each feed, sometimes less at 70-90ml during dream feeding at night. I was wondering if anyone else has been told this, and how long to continue waking him every 3 hours for a bottle, as opposed to him letting us know when he's hungry? I'm super confused over how long to do this for as he gets older. What advice have others had, as some other mum's I've spoken to have never heard this before, and what do you do with your LO's?
