Features and How to Choose Pull-Up – M Diapers
A pull-up diaper size generally recommended for babies weighing 6 to 12kg, often used from the crawling stage through cruising. M size is one of the longest-used diaper sizes and is often purchased in large quantities, so cost performance matters. Choosing diapers with a secure waistband can help prevent slipping even when your baby wears pants over them. Bulk purchases and subscription-style buying can be smart ways to lower the price per diaper.
