2nd trimester to do list?

Hey everyone, so I’m a stay at home mom (or future mom)😂. I’m 20 weeks pregnant and was wondering what to start doing.

I feel super bored all day while my SO is at work and i feel useless almost. Not like useless as in a depressed way, but useless as in i feel like i don’t do anything all day.

I want to start preparing for baby, as I’m now halfway done and not a single thing has been done. Is there anything i can start buying or preparing for when baby comes?

I already know the gender, it’s a little boy. I already picked out nursery theme and his name, also I’ve started the registry-if that helps!
