Second time moms: gift ideas

Hi Redditors! My friend is expecting a baby boy, her second child, and already has many things that they need (like stroller system, bassinet, sleep sacks, etc.)

Outside of some clothing (her first was a girl), I'm struggling to think of what else she might appreciate or want the second time around.

I'd love some gift suggestions! I already ordered her an adult sleep sack since they coslept with their first, and plan on doing it again with their second. I'm also contributing to their night nanny fund. But I'd like to gift something to specifically baby boy.

So if you've had more than one child, I'd love to have your suggestions! What do you wish you had the second time around?
