Any must haves for a second child?

Chelsea • Ezra 10/25/16, baby girl coming June 2019 🤗

Hey moms! I’m currently 27w pregnant with my second child, and since I’m having a girl this time (I have a 2.5yo boy) my family is throwing me a small sprinkle! I have a small registry for mostly girl clothes and girly things, but are there any items you feel was a lifesaver or a must have for 2 kids? I did register for a double stroller and a baby carrier, but I feel somewhat lost on what would be needed with 2! Thanks so much in advance 🤗
