Kiddos is an online marketplace where families can buy, sell, and give away new and pre-owned clothing and other items for children and mothers. Founded from a mother’s wish to give well-kept children’s clothes a new home, the platform brings parents and sellers together for convenient, more sustainable shopping. Its selection includes children’s clothing and footwear, baby and child equipment, and items for mothers, with products listed across age groups, sizes, brands, and categories.

Customers can browse and filter listings, while sellers create a storefront and post items through the platform. Kiddos highlights affordable prices, with some products starting at 150 Serbian dinars, and says buyers can save up to 70%. Payments are made through the platform rather than directly to sellers. Kiddos also offers customer support and a money-back guarantee when an item does not match its description. For sellers, the stated fee is 10% plus 15 dinars per transaction, with shipping protection if a buyer does not collect a parcel.
