Why I Believe a Sleep Sack for 12-18 Months Old is a Necessity

As a parent, one of the most important things I have learned is the significance of quality sleep for my child’s overall health and development. And when it comes to ensuring a good night’s rest, having the right sleep gear is crucial. That’s why I strongly believe that a sleep sack for 12-18 months old is an absolute necessity.

Firstly, at this stage, babies are becoming more mobile and active, making traditional blankets and swaddles unsafe as they can easily come loose and potentially cover their face. A sleep sack eliminates this risk by securely wrapping around their body, providing warmth without the danger of suffocation.

Moreover, sleep sacks have been recommended by pediatricians as a safe alternative to blankets and swaddles for infants. They are designed to keep your little one at a comfortable temperature throughout the night, reducing the risk of overheating or becoming too cold. This helps create a soothing environment for better quality sleep.

Another reason why I swear by sleep sacks is their ability to promote healthy sleeping habits. The snug fit of a sleep sack gives babies the feeling of being swaddled while still allowing them to move their arms

My Buying Guide on ‘Sleep Sack 12-18 Months’

As a parent, I understand the struggle of finding the perfect sleep sack for your little one. After extensive research and personal experience, I have compiled a buying guide to help you choose the best sleep sack for your 12-18 month old.

1. Material

When it comes to choosing a sleep sack, the material is crucial. It should be soft, breathable and comfortable for your baby’s delicate skin. Look for sleep sacks made of 100% cotton or bamboo as they are hypoallergenic and gentle on the skin.

2. Size and Fit

It is essential to choose the right size for your baby’s comfort and safety. A sleep sack that is too big can cause suffocation hazards while a small one can restrict movement and cause discomfort. Measure your baby’s height and weight accurately before buying and check the size chart provided by the manufacturer.

3. TOG Rating

TOG (Thermal Overall Grade) rating indicates the warmth level of a sleep sack. For 12-18-month-old babies, a TOG rating of 0.5-1 is recommended as it provides enough warmth without overheating. However, it may vary depending on your baby’s room temperature and season.

4. Zipper or Buttons?

Sleep sacks come with either zippers or buttons for closure. Zippers are more convenient for quick diaper changes but can be uncomfortable if they dig into your baby’s skin. Buttons are safer but may take more time for diaper changes, especially during nighttime.

5. Weight Limit

Most sleep sacks have a weight limit mentioned in their product description or packaging. It is crucial to follow this limit to ensure that your baby is safe and comfortable while sleeping.

6. Brand Reputation

It is always advisable to buy from trusted brands with good customer reviews when it comes to baby products like sleep sacks. They use high-quality materials, ensure safety standards, and provide better customer support in case of any issues.

7. Ease of Cleaning

With babies come spit-ups, spills, and other messes that require frequent washing of their clothes, including their sleep sacks. Look for machine-washable sleep sacks that are easy to clean and maintain.

8.Budget

Sleep sacks come in various price ranges depending on their brand, material, size, etc.. Decide on a budget beforehand to narrow down your options without compromising on quality.

In conclusion,, choosing the right sleep sack for your 12-18 month old involves considering factors such as material, size & fit, TOG rating, closure type, weight limit, brand reputation, ease of cleaning and budget. By keeping these factors in mind and doing thorough research before making a purchase decision will ensure that you find the perfect sleep sack for your little one’s peaceful slumber.
