At Boho Baby, we focus on sizes 0–3 and 3–6 months because newborn sizing can vary greatly between babies and is often outgrown very quickly. Many newborns only wear these sizes for a short time while spending most of their early weeks in zip suits. Once babies begin growing and becoming more active, rompers and playsuits become a much more practical and comfortable outfit choice. Our range is designed for babies from around a few weeks old through to 12 months, when parents get the most wear and value from these styles.
