In the end I promise you none of it matters. You'll figure it out with trial and error. Sometimes a little more error than trial but you'll figure out what works for you. You'll be tired. You'll be cranky. You'll feel at times like you are failing. Sometimes you will be. But in reality even then you are probably NOT actually hurting your kid.
My 5 year old son and 5 month old daughter died in a car crash in 2010. There is only one piece of advice that I give people. Take video, lots of video of your kid. Video of them rolling around on the floor making stupid noises, laying next to the dog, trying to roll over, making a crazy face when you try to feed them prunes. As they get older the tendency is to stop taking every day video. Don't wait until they are up to bat, or playing the piano, or dancing. Those videos are great for grandma and grandpa who can't be there but 99% of them never get watched again and the 1% that do probably don't come out until the high school graduation party. Pull out your phone once a week and ask them about their day. If you see them playing in the corner take out your phone and record them. Ask them what they are doing. Their imaginations are priceless. Pictures are great, and you should take a ridiculous amount of them but video is king. When they are older listening them talk about an episode of Thomas the Tank Engine or Veggie Tales is amazing. Their voice and movement conveys their personality so much more than a picture can. My most treasured memories are the videos of them doing nothing special. For what it's worth.
