I suspect DD2 has more of a routine than I've really registered
We're 100% baby led too. However, with a 3 year old and her activities and such, we spend much of our days on the go - Kindermusik, Little Gym, play dates, parks, etc. It's very different from when DD1 was a baby and we spent most of our days at home, and the timing of outings was purely based on what was going on with one baby.
We do have a general routine of wake - some happy cooing time and diaper change with Daddy before he leaves for work, then leisurely nursing with some cooing added in until she eventually falls back asleep for a pretty short morning nap.
Then generally big sister gets up, we all get dressed and ready and go where ever that day will take us. Our leave time varies by an hour or more. Some days DD2 seems more fussy than others in that time frame, and I often think she'd prefer I just sit and nurse her back down. As soon as I'll dressed I stick her in the sling while I finish getting us ready and she'll often fall asleep before we get in the car.
When we're out she'll generally sleep in the sling, or wake up and watch things in the sling. We nurse whenever she wants. She does longer stretches between nursings than DD2 did - more of the every 1.5-3 hours instead of the almost constant here and there nursing of DD1. She almost always sleeps in my lap or in the sling. This week we've had more out of arms naps than usual - she took a nap in her hammock on both
Monday and Wednesday
Since she's really always on me, her sleep and awake times just flow pretty naturally and I really don't watch a clock.
In the evenings we do a pretty long interval of nursing/napping and she's pretty insistent on having me and nursing lots. She does more sleep nursing during that time too. DD1 regularly nursed in her sleep, waking as soon as I considered unlatching her. DD2 does it much less.
I generally get a 5-7 hour stretch of sleep at night!!! Some nights it's more like 3-4 hours. However, DD1 did 4-6 hours a night until around 4 months, so I'm not anticipating keeping the long sleep time - if we do I'll be pleasantly surprised.
