In the category of “no universal truths for babies”… my partner and I were hesitant to use pacifiers due to some of the negatives around jaw and mouth development (zero judgement for people who do use them). We agonized over whether we were overthinking it, whether it would help him sleep… but eventually we broke down and gave our kid one. To our surprise, he hated it. Wouldn’t keep it in his mouth at all, and all our thinking was for nothing.
