I chose Tushbaby for the stage when your child wants up, down, and back up again before you'd finish fastening a full carrier. The wide hip seat helps support their weight while the waistband shifts more of the load away from your arms. Built-in pockets can replace a separate bag for quick errands.
Safety matters: Tushbaby is not hands-free. Keep one arm around your child. From birth, the seat can be used as feeding support. Face-to-face and side carries begin after baby has steady head and neck control, usually around 4 months; forward-facing use begins around 6 months. Follow the manufacturer's position and fit instructions for your child's stage. The stated limit is 36 months or 45 pounds.
A fit note: The storage is genuinely useful, but the structured seat is bulkier than a sling and can feel warm. Hip carriers also fit bodies differently. Wear it high and snug, and expect to keep supporting your child rather than walking fully hands-free.
