What is your mommy “must have” product

Courtney • Trying for #2, First baby born July 2020 👶

This question is for the ladies that have cared for a newborn in the past 5-10 years. What product or thing could you not live without. Please feel free to add specific brands and models. Was it a swing, a diaper bag, noise machine? Something else entirely? Please help a mommy out! Any great Amazon finds? Any baby shower gifts that turned out to be extremely useful?

Thank you in advance for your replies!
