My Buying Guide on ‘Big Sister Shirt 18 Months’

As a parent, I understand the excitement and joy of welcoming a new addition to the family. It’s always a special moment when your little one becomes a big sister, and what better way to celebrate this milestone than with a cute big sister shirt? But with so many options available in the market, it can be overwhelming to choose the perfect one for your 18-month-old. Don’t worry; I have put together this buying guide to help you make an informed decision.

Determining the Right Size

The first thing you need to consider when buying a big sister shirt for your 18-month-old is the size. Children grow at different rates, so it’s essential to measure your little one’s chest and height before making a purchase. Most brands have their own size charts, so make sure to check them before placing an order. It’s always better to go for a slightly larger size as children tend to grow quickly at this age.

Made from Soft Fabric

Comfort is key when it comes to clothing for toddlers. As they are constantly moving and playing, it’s essential to choose a big sister shirt that is made from soft and breathable fabric. Cotton is an ideal choice as it is gentle on their delicate skin and allows air circulation. Additionally, opt for shirts that have tag-less labels or tags that are stitched on the outside, as they can be irritating for your little one.

Finding the Right Design

Big sister shirts come in various designs and styles, from simple text prints to cute graphics and illustrations. When choosing a design, keep in mind your child’s personality and preferences. If they love bright colors, go for a shirt with vibrant prints. If they prefer something more subtle, opt for pastel shades or minimalistic designs.

Consider the Occasion

Another factor to consider is where your child will be wearing the big sister shirt. Is it for everyday wear or a special occasion? If it’s for everyday wear, then a casual t-shirt style would be appropriate. However, if you’re planning on taking pictures or attending an event with your little one wearing the shirt, then opt for something dressier like a polo or button-down style.

Read Reviews

Before making any purchase online (or even in-store), always take some time to read reviews from other parents who have bought similar products. This will give you an idea of the quality of the product and if it will meet your expectations.

Set Your Budget

Last but not least, set a budget before starting your search for a big sister shirt. While there are plenty of affordable options available, keep in mind that quality comes at a price too. Settling for cheaper options may result in poor quality fabric or print that may not last long.

In conclusion, buying a big sister shirt for your 18-month-old should be an enjoyable experience rather than stressful. By following these tips and considering factors like size, fabric, design, occasion, reviews and budget; you can find the perfect big sister shirt that will make your little one feel proud and excited about becoming an older sibling!
