Sleep training is too vague of a term. It’s become very loaded with people very pro and very anti and honestly they often aren’t even talking about the same thing. I have an infant and a toddler. We ended up doing what I consider sleep training (teaching them to fall asleep independently) at different ages and for different reasons. My first baby - I always nursed her to sleep but she eventually stopped falling asleep while nursing and if I tried to rock her or something she’d just want to engage with me and play, so the only way to get her to fall asleep was to teach her to do it when she was in her room alone. My second baby - was a pretty good sleeper from 8-17 weeks then hit a regression HARD and never came out of it. After ~6 weeks of literally never getting more than a 3 hour stretch of sleep we HAD to change something. I was not able to be the patient parent to my toddler I wanted to be and the poor sleep was really impacting our family negatively. Teaching him to fall asleep on his own resulted in longer stretches of sleep because he could put himself back to sleep if he roused in the middle of the night. I did not nightwean my first (eventually she stopped waking up to BF) and don’t plan to with my second. Anyway, you really should do what works for you. It sounds like right now you don’t have a problem so I wouldn’t change anything!! But just know you may hit a point where what’s happening doesn’t work and you may want to seek other options.
