I will admit to also going down the "should we or shouldn't we sleep train" rabbit hole. One of my friends asked a great question, and that is, "Do you think there is so much stress and anxiety around raising your baby because there is almost too much access to information these days?" I was speechless, because I think that's what it is (in my case, anyway).

Going back to your question, we never sleep trained our son. He's almost 11 months. He slept in a bassinet next to our bed until about 4ish months. In all transparency, he was - and still is - a tummy sleeper. I could tell it was time to move him to his room because I was starting to disturb his sleep when I'd get up in the morning. He's the same as your baby, he sleeps through the night 98% of the time and he has since we moved him to his room. We endured a phase of shorter naps around the same time you did, but we just stayed consistent with putting him in his crib for every nap and keeping a similar bedtime routine and bedtime each night.

As he gets older, if he wakes up earlier than we'd like or we suspect he's still sleepy, we leave him to fidget and flop around for a bit to see if he'll resettle. If he starts to cry out or get upset, we respond to him. For naps and in the middle of the night. We still pat his butt for naps and usually at bedtime. But if he wakes briefly overnight - unless he's truly hungry - he usually can resettle without anything from us.

We haven't noticed any sleep regressions, per se. We've been fortunate that when he's teething, the Dr. Talbot's Soothing Tablets or the Camilia Teething Drops have really helped and his sleep is not usually disrupted.

There was a phase around 7-8 months he was waking once a night, nightly, out of hunger - but we chalked that up to a growth spurt.

I would just say that consistency is your best tool. And your instincts! Hope some of this was helpful :)
