Finding the perfect fit isn't just about comfort — it's about warmth and hygiene. Always refer to the baby underwear size chart on the brand's website before buying.

Each brand has unique sizing based on age and weight. For example:

Size 0 (6M–12M): Ideal for babies transitioning from diapers to underwear.

Size 1 (1Y–2Y) and upward: Perfect for toddlers learning independence.

If your child is between sizes, go for the bigger one for flexibility and growth.
