Why Baby Girl Swimsuit 12-18 Months is a Must-Have

As a mother of a 12-month-old girl, I have come to understand the importance of having a swimsuit specifically designed for her age. Here are a few reasons why I believe every baby girl needs a swimsuit in the size of 12-18 months:

1. Protection from the Sun: Babies have delicate and sensitive skin that can easily get sunburned. A swimsuit with UV protection can help shield their skin from harmful UV rays while they enjoy playing in the water.

2. Comfort and Mobility: A proper fitting swimsuit allows for easy movement and comfort for your little one. It will not only make them feel more at ease but also help them build confidence as they explore and play in the water.

3. Hygiene: When it comes to swimming pools, hygiene is crucial, especially for babies who have weaker immune systems. A swimsuit acts as a barrier between your baby’s skin and the pool water, reducing their exposure to any bacteria or germs.

4. Cute Factor: Let’s be honest; baby girl swimsuits are simply adorable! Dressing up your little one in a cute swimsuit is not only fun but also

My Buying Guide on ‘Baby Girl Swimsuit 12-18 Months’

As a parent, I understand the importance of choosing the right swimsuit for my little one. It should be comfortable, stylish and provide enough coverage for their delicate skin. Here is a buying guide to help you find the perfect swimsuit for your baby girl aged 12-18 months.

Size Matters

When it comes to buying a swimsuit for your baby girl, size is crucial. Babies grow quickly, and choosing the right size is essential to ensure a comfortable fit. It is recommended to buy a swimsuit that is one size bigger than your baby’s current clothing size. This will allow room for growth and ensure that the swimsuit can be used for an extended period.

Fabric and Material

Babies have sensitive skin, so it is important to choose a swimsuit made from soft and gentle fabric. Look for swimsuits with high-quality materials like nylon, spandex or lycra blend. These materials are soft, stretchy and provide UPF (Ultraviolet Protection Factor) to protect your baby’s delicate skin from harmful sun rays.

Style and Design

When choosing a swimsuit for your baby girl, opt for designs that are cute and comfortable at the same time. Ruffles, frills, bows or floral prints are popular choices for baby girl swimsuits. Make sure there are no sharp edges or embellishments that could potentially harm your little one.

One-Piece vs Two-Piece

One-piece swimsuits are ideal for babies as they provide full coverage and protection from the sun. They are also less likely to ride up or shift while your little one plays in the water. However, if you prefer a two-piece suit, make sure it has secure closures and fits comfortably around your baby’s body.

Sun Protection

Sun protection is vital when it comes to swimwear for babies. Look for swimsuits with UPF 50+ rating as it blocks out 98% of harmful UV rays. You can also opt for swimwear with long sleeves or rash guards that provide additional coverage.

Easy On/Off

Babies can get fussy during diaper changes, so choose a swimsuit with easy on/off features such as snaps or zippers at the bottom. This will make diaper changes quick and hassle-free.

Durability

Babies love to explore their surroundings, which means their swimwear needs to withstand all their activities. Look for high-quality stitching and durable materials that can withstand wear and tear without losing shape or color.

In conclusion, when purchasing a swimsuit for your baby girl aged 12-18 months, consider factors such as size, fabric/materials, style/design, sun protection, ease of wear and durability. By keeping these tips in mind while shopping, you can find the perfect swimsuit that will keep your little one comfortable and protected while having fun in the water.
