Sleep Training, or Not

I have a confession. William isn’t sleeping through the night yet, and I kind of don’t mind. Don’t get me wrong. I do mind the forgetful mushy brain that creeps into my workday, but I don’t mind these quiet moments.
He was sleeping pretty well until he started teething. There are some other factors involved. I have spent too much time getting Estelle to sleep all night for almost 5 years, and the results are mediocre. STILL. Why bother? I might just ride the wave, and see where William ends up. I have resources and know-how if I want to course correct. Also, soothing a baby without picking him up is kind of hard to do when the kids share a room. Seemingly endless crying is involved, and nobody wants both kids up at the same time. Has anyone had much luck with shared rooms and getting babies to sleep for longer stretches?

While we are on the subject of sleep, I might just skip folding laundry in favor of an early bedtime.
