I'm not going to judge you if you chose to do that because it worked for you, if your kid didn't sleep comfortably on his own, or didn't settle, or whatever, but don't frame it as its detrimental to the kids who sleep trained with no issue, that's why people take it personally. I don't sit here and say your kid is going to become snowflake soft because you coddled him to sleep, so why would you say my kid is going to have trust issues? This is the problem with the non sleep training group, they claim some bizarre thing about maladjusted kids because of detachment syndromes because they sleep in their own bed? I'm sure the evidence is well supported in some helicopter parent groups, where the groupthink is the same. My kid, at 5 months, knows when its bedtime, get read a story, listens to some lullabies, get heavy eyes and blinks, gets placed in his crib BEFORE he is asleep so he doesn't wake up confused and feeling abandoned because he knows he was there before he fell asleep, and sleeps fine through the night. He's happy as shit all day long, plays, trusts, eats, learns, etc. This took no time, and virtually no effort, with no cruelty, no "letting him cry endlessly until he figures it out".
I'd love to see these "studies" you're referencing. Allow me to do some of the work for you
