must haves for baby 👶🏼

what is your must haves for baby? i have a checklist going and trying to make sure I haven't forgotten anything. so what's that one product(s) you just "have to have" lol.. 
mine are: 
• medela sonata breast pump 
• 4moms breeze playard 
I had the medela pisa (pump in style advanced) with my last baby 3.5 years ago and also had the mamaroo. loved each of the products so much that I have to have more of them with this sweet little. both are huge winners!
