Baby completes 1 month today. Any advice for Month 2? What to do and what not to do? - New Dad

1st couple of weeks were crazy but now finding some rhythm. Sleeps for 2+ hours straight at night. Very patient and strong baby (in our opinion), thanks to God. With more feeding, was even able to reach 3.5 hours tonight, not sure if that's going to stay. Colic has been a minor thing, the drops do help though.

What activities should I do with my little girl now? Any books or youtube channels you'd recommend? When she sleeps at night, does make some sounds which make us rock the crib with the fear that she might wake up if we don't. Should we continue that or ignore the sounds unless it's crying? Thank you!
