eh my first born could have written your guide,
except without watching that clock that was his basic schedule.
He was, what I like to call, an Easy Keeper. Easy to settle, easy to work with, easy to get to sleep, easy going.
He's still that way as a 15 year old.
His younger brother, however, is a high needs personality. He needs less sleep than I do, and always has. as an infant he slept for 15 minutes at a time.
no amount of charts, or setting, swaddling, white noise, changing schedules or anything else worked for him.
Your suggestions work fairly well for easy babies.
difficult babies, your suggestions may make a mom feel like she's STILL doing everything wrong if she can't make your wonderful sounding suggestions work out for her.
Besides the fact that when you interfere with a basic human need to eat and sleep by scheduling and overscheduling everything for an infant, they learn to eat by the clock, sleep by the clock and not listen to their own needs. THAT can cause long term sleep and eating problems, that may not be seen until adolescent or teenaged years.
pay attention to the baby's needs first, not the schedule, no matter how good it may sound when listed on a message board for sleep deprived parents of 0-3 month old babies.
