Why You Still Need a Second Baby Registry
One of the biggest perks of using a second baby registry checklist is making sure you don’t forget essentials while juggling a toddler and a newborn.
Even if you saved everything from your first baby, a second baby brings new dynamics:
- You’ll need doubles of everyday items (like burp cloths and bottles).
- Some items expire or degrade (car seats, pacifiers, bottle nipples).
- Second-time parenting often means optimizing for convenience and efficiency — think compact gear, grab-and-go essentials, and sleep aids.

Feeding Must-Haves for Baby #2
Whether you’re breastfeeding, formula-feeding, or a combo, here are the must-haves to restock:
