FATE - I have 3 dc, they have all been pretty good sleepers from 6 months and ds was a good sleeper form day one.
none of them fit your patterns
dd1 and dd2 would not take dummies.
ds would not feed 'little and often' he fed at 3 hours on the dot (his choice not mine)
Only one of mine liked swaddling, ds would scream the place down if you swaddled him, he liked to lie on his back all 4 limbs stretched out.
Only one of mine slept as much as yours did during the day, ds slept for 3 naps and then 2 of 1-1,5 hours. He slept very well at night, sleeping through from 6 weeks.
Your 6-12 week figures didn't apply to any of mine, they were all awake for far far more time than that. They were awake to 2 hours, then nap.
I find the idea that babies should only be held when they are feeding bizarre, we held ours in order to play with them! Did your babies not enjoy being smiled at, tickled etc???
None of mine would ever sleep in a bouncy chair, they wanted to be flat, and ds wanted to be in a dark quiet space, not sleeping in the kitchen/living room in a bouncy chair.
14 weeks sleeping half and hour every 2 hours plus 2 longer naps??
No way would any of mine have slept that much, they did the longer naps not the shorter ones in between.
I understand the principles you are stating, and in agree in principle with you, we did very strongly that 'feed in day and night time = sleep dream feed' etc. we established routines etc.
But I think your figures about sleep times etc are pretty much YOUR baby/babies and not all.
It may be different that my one who slept lots was an early baby (38 weeks) and the other 2 late babies (42 weeks) so don't know if that makes any difference.
I would hate anyone reading this to be worrying about getting your sleep patterns
