Looking for advice (or probably reassurance!) re routines. My baby is 8 weeks old and we very much just go with the flow each day so no two days look the same. From being about two weeks old she seemed to naturally start settling for the night around 11ish (I used to worry this was late for a baby but now realise totally normal for tiny babies). She used to cluster feed then conk out around that time. The cluster feeding seemed to stop around 4 weeks (coincidentally when I learnt about wake windows and started encouraging naps in an evening) but we've kept the same rough routine of bath around 9:30-10, feed and popped in her cot around 11ish because it works for her and us. In an evening now we just encourage naps and feeds until we're ready to go up to bed. She normally wakes twice through the night and up for the day between about 8:30-9:30 which is great. I try to keep an eye on awake time throughout the day to make sure she gets plenty of daytime sleep.
Now my worry is that at some point this will need to change and I'm already worried about changing a good thing! I know she's still too tiny for a rigid routine and not looking to introduce that as we prefer the flexibility but wondering when do I need to start thinking about introducing a more structured routine rather than just going with the flow each day? I'd rather keep her downstairs with us until we go to bed until she's 6 months because of sids advice but is this too late?! I'm probably (most likely) overthinking and know sleep regressions are going to mess with things anyway. Anyone done similar until 6months and it's not been a complete disaster?!
