Most babies transition to size 2 diapers around 2-6 months old, though timing varies with individual growth patterns. Active babies who are rolling and moving more may need the extra room and protection that size 2 provides. Weight is always a better indicator than age for proper sizing.
What weight are size 2 diapers for?
Size 2 diapers are designed for babies weighing 12-18 pounds. This weight range typically covers active infants who are becoming more mobile and curious. The roomier fit accommodates growing bellies and increased movement throughout the day.
When to change diaper size from 1 to 2?
Make the switch when your baby reaches 12 pounds or shows signs that size 1 is getting snug. Look for red marks around the waist, frequent leaks, or difficulty fastening the tabs comfortably. Many parents size up when they notice their baby seems uncomfortable or fussy during changes.
How to know if a diaper is too small?
Watch for red marks or indentations around your baby's waist and thighs after removing the diaper. Frequent leaks, tabs that barely reach the front panel, or difficulty getting two fingers under the waistband also signal it's time to size up for better comfort and protection.
