As a parent myself I have only one piece of child rearing advice. First: Read a bunch of books (which will contradict each other) Then: a) do what you think is right and b) when someone tells you to do X (especially, but not only your mother or mother in law), if you disagree just say "Funny you should say that because I just read the exact opposite" and hand them a random baby rearing book. This sounds like a joke b…
Worse: The books that most resonate with you may well be the ones you need to ignore.
Take strict vs permissive parenting, for example. Say you're by nature a more permissive parenting. The books that say you should be permissive will resonate more with you than the books that say that you should be strict. But it's the ones that say to be strict that you need to hear, because they're the ones that are against your natural bent. (Nobody needed to tell you to be permissive, you were going to do that anyway.)
(My position here is that either strict or permissive, taken too far, will be problematic. So you can swap strict and permissive in the previous paragraph, and everything is still true.)
So don't just read parenting books and listen to the ones that strike a chord with you. It's the other ones that you need to carefully consider what they say.
