Oooh congrats on the twins, mama! A few of us in my mum circle have twins and honestly, the game-changer products are a good double stroller (we swear by ones that fold compact for our cars), two of everything for feeding/sleeping setup, and a reliable baby monitor with two channels so you can see both nurseries. One of my friends also invested in a feeding pillow designed for tandem nursing because it saved her sanity during those early months, definitely worth it if you're planning to breastfeed! What kind of setup are you thinking about, and how far along are you?
