Having now accepted that I also accept that I'm not in fact a failure of a parent if all he wants to eat today is chicken nuggets and chips, and that we're making progress in helping him to try new things.
Don't subject yourself to ridiculous expectations, learn the basics, and then take solace that at least for the first few months if everyone is fed, clean, and clothed then you're winning.
The other thing you will sweat is the newborn stage. You will try your hardest to get them to sleep only to panic because they are quiet, waking them up in your efforts to make sure.
One thing I do know: I changed the day my first child was born. What used to matter to me, things at work that bothered me, do not matter as much anymore. How can it? The most precious and beautiful thing is your child and all the damn hair they make you tear out!
Turns out for me it worked perfectly, maybe because I was more in listening mode rather than trying to apply things I read in books.
In any case, I would advise to just trust your guts. If you feel like you want to know a lot, just read! Congrats in advance, and enjoy the first months as much as you can! Becoming a parent is the best thing that can happen to you :)
The big one is sleep. A book on sleeping routines usually always help everyone. The contented baby handbook is a good one.
The problem with reading books before hand is that a lot preach to an unrealistic ideal. You will find what works best for you, your partner and baby afterwards. It's the only way.
