I feel like I should know more?!?!?

I'm 18 weeks with my first, I feel like I don't know very much about anything. 😞I have taken care of babies before of course, but I work full time & when I come home I'm usually cleaning up or cooking, taking care of my animals, or trying to relax a little!! I feel like i should know more about what kind of bottles I want, what kind of stuff I'm going to put on my registry, & just more about my baby is general! How can I go about doing this or what are some things I can do to be more informed?!
