Its interesting to see peoples routines, I feel like I'm a slave to mine and not sure how people go to baby groups (pre pandemic!) etc as I feel I'm always having to work around feeding / nap times.
We normally wake up between 6 - 6.30.
Nap 1 is 8 or 8.30, basically 2 hrs wake time from when he wakes up.
Nap 2 will be 2 and a half hours after he wakes up from nap 1 so can vary. His first nap can be anywhere from 50 mins to 1h 10 mins. Nap 2 probably around 11.45am. Again length varies, usually 45 mins to an hr and 20 occasionally longer. 3rd nap will be 2 and a half hrs after he wakes up and be around 3.30 or 3.45 and will be shorter, about 30 or 40 mins.
I find I really have to try and stick to this and it's hard with the timings. For example, if I go for a walk in the afternoon and hes been awake for a n hr and a half he will actually fall asleep in the pram but this is bad news as he will then only sleep 30 to 40 mins and not be tired for his nap after that and be awake far too long before bed. Not sure if I'm trying to control the day routine too much 
Bed time routine starts at 6.15 with a bath. Hes out the bath at 6.35 and into pjs and then hes given his last bottle at 6.45 in a dark room. I put him down awake at 7pm and by 7.05 hes asleep. He doesnt usually stir then till he wakes up which I know I'm fortunate with. Recently, for the first time in months, he has woken about 3 or 4 times, cries for 30 seconds then goes back to sleep. I think it's the beginning of teething!
