How do they work together? LO is 14 weeks & I've followed her lead for feeding & napping. Her bedtime varies each day from 8-9.30. How do you establish a routine when you don't know when the feeds are going to be?
Mine was in a routine give or take an hour each way at around the 14 week mark. I didn't really 'impose' anything, just sort of 'nudged' things around so they eventually ended up roughly where I wanted them.
The most helpful thing I found was to break the habit of 'snacking' where I was constantly feeding him thinking he might be a bit peckish - actually he was happy to go for anything from 3 to 4 hours between feeds by around 10 weeks.
Once he was taking bigger feeds instead of snacks I was able to get into more of a routine because he'd be full for longer - it was never exact but it meant that whatever time he woke for his first feed, I'd be able to work out roughly when each feed might be during the day so I could plan my day a bit better (obviously it would go out the window if he puked up!). It also left decent time between feeds for napping (if he ever felt like it!).
By 14 weeks he was waking up at almost exactly the same time each morning so the routine became more reliable because his sleep pattern became more reliable.
