Big Babies 6-18 months

Big Babies 6–18 months brings together baby gear for the stage when little ones are sitting taller, moving more, and needing new ways to eat, play, travel, and wind down. You’ll find practical picks across high chairs, booster seats, playards, wagons, playmats, bath time, potty, and safety essentials, plus a strong mix of car seat options that fit growing routines.

This collection is designed for everyday transitions: a pack and play for travel or naps, a booster seat for mealtime, a wagon for outings, or floor seats and play spaces for active play at home. It’s a smart place to shop if you’re updating gear as your baby outgrows the newborn stage and you want options that match real family life.

At REBEL, these finds come from open-box, overstock, and other never-used inventory sourced from top brands and retailers—not secondhand from private sellers. Every item is professionally inspected before listing, so you can shop big-kid baby gear with smaller tags and less guesswork.
