I let my friend that has a one year old try this out. This is what she had to say: I love this product! You can heat it up to keep your child warm or freeze it to keep them cool. Very lightweight and comfortable. Great for just having at home or traveling with. My daughter is 14 months old and she usually hates anything being on her, but this product was lightweight and comfortable enough that she did not mind having it on. It’s great for car rides when your AC is not working. I would put this behind my daughter on car rides to keep her cool or warm and it worked great. Soft and comfortable enough that she didn’t even noticed it while she was in her car seat. I would definitely recommend this to any parent.
