Splash About Baby Snug Happy Nappy Wetsuit Apple Daisy Apple Pattern L Size (Although the package indicates 3-6 months, this is the L size for 6-14 months.) Due to the packaging size, a hanger is not included. Here are some actual usage impressions: ・Size The manufacturer's weight guide indicates 10-15kg, but I think it might be suitable for slightly smaller babies as well. My child also used the same one, but at 8.3kg, they became chubby and outgrew it. They are now 2 years old and a little over 11kg, and use the XL size. ・Diaper Function We used it for baby swimming lessons 2-3 times a week, and it saved us money because water play diapers are quite expensive. ・Heat Retention When the pool water was cold, they often shivered, but since switching to this, or perhaps because they have become more energetic, or maybe it's seasonal, I don't know, but I noticed they stopped shivering.
