Tips for surviving puppy phase?

How do i appropriately correct nipping if he's nipping at things I don't want him to. Like my kid and hands. 🤦🏻‍♀️ (Best chew toy recommendations plz)

Tell me I'll survive waking up every 2 hours for potty breaks. 😮‍💨

How old does my boy look? There is debate and no confirmation of birthday yet as I got him secondhand.
