Yes, Baby Riddle offers free shipping on orders over $150. Many of our kids birthday outfits and pajama sets qualify for free shipping on their own, or you can bundle items from our birthday collection to reach the threshold.

Check our shipping policy page for the latest details and any current promotions.

We recommend ordering at least 7 to 10 business days before the birthday to allow for standard shipping. If the birthday is within the week, check product pages for items marked as in-stock and eligible for expedited shipping.

Popular styles in key sizes (like 12M, 18M, and 2T) can sell out quickly so ordering early is always a good idea to avoid disappointment.

Baby Riddle accepts returns on unworn, unwashed items with tags attached within 21 days of delivery. If an outfit does not fit or is not quite right, you can request a return or exchange through our website.

Please review our full returns policy page for complete terms, exclusions, and instructions on how to start a return.
