We have a "pattern" to the day but it doesn't revolve around times.
Same here so far. I try to get 3 sleeps in but the timing is pretty flexible depending on when DD wakes and whether she shows tired signs. Bedtime is somewhere between 6-7pm depending on the previous points as well. I find the 'routine' we use is the bedtime 'cues' hence DD knows its now time for sleep & this works well.

That said DD is only sleeping in her bed so far. Next step is to try sleeping in the pram/carrier while we are out. But it is early days for us anyway. The 'routines' I've roughly based ours around is Safe Sleep Space and BabyBliss but I don't 'follow' their routines per se rather use them as a guide.

I find I can make plans for the morning and later afternoon quite safely but I let the middle of the day be quite fluid and on our terms. I hope to be more flexible over time. I think if DD can get one good sleep in the day then I will be more flexible with the others.
