FAQ'S

Choose clothes that allow free leg movement and don’t bunch at the ankles. Convertible/footless options are helpful for traction, and soft waistbands make outfit changes easier during busy days.

When dressing your 9 month old baby, opt for durable options designed for comfort and mobility. As your baby grows, dressing them in clothing that allows for freedom of movement is key to their comfort and development. Consider soft convertible footies that can transition from sleepwear to playwear or   classic bodysuits paired with versatile pants or leggings for a stylish yet practical look. They'll also need cozy sleepwear for naptime and bedtime, like cozy sleep sacks and soft pajama sets. Day or night, choose soft, breathable fabrics that promote comfort and protect sensitive skin. Additionally, avoid clothing with small parts, such as buttons, that may pose as choking hazards.

Babies typically start wearing 12-month clothes around the age of 9 to 12 months. However, this can vary depending on the individual growth rate of the baby. Some babies may transition into 12-month clothes as early as 6-9 months old, while others may continue wearing smaller sizes for a bit longer.

While numbered sizing can be used as a guide, always remember to consider your baby's height, weight, and overall comfort when determining the appropriate clothing size. Additionally, since sizing and fit can vary from brand to brand and product to product, we recommend consulting the brand’s sizing chart to help you find the ideal size for your baby.
