The routine part I took to mean doing the same things regularly, or in the same way, not at exactly the same time. OP put it perfectly! And Tanstar too!

Our 'routine' things were the bedtime routine (order of doing things) - bath, massage, feed, bed then quiet feeds in the dark at night. Daytime routines for us meant things like having a little tummy time each day, a consistent way of putting him down for naps (a repeated phrase, lots of cuddles, slightly darken the room - though he'd be in different places each time) and feeding on demand.

If people asked me if If I followed a routine, I'd just say 'yes'. I found most people just wanted to hear that, they didn't care that their version might be different from yours iykwim. They don't really care what it is, they just heard the word and think it's important. If they're parents and you ask them what their routine was for their baby at that age, I wonder what they'd say...
