A lot of people are searching for breathable baby blankets. It makes sense to reduce the chance of impaired breathing if baby gets wrapped up in a blanket. Some say not to use a blanket (or any bedding material) before 12 months, but others see that as extreme and instead opt for breathable baby blankets.
Cotton muslin is often recommended, but we think that a knitted baby blanket is even more breathable. Think about the knitted hats and scarves you've worn - perhaps made by your grandmother. As you can see in the image here, there is space between each strand of yarn, and even more so when it is stretched a little - plenty of space for air to pass.
Why aren't knitted blankets mentioned more often for this topic? It's because these blankets are often homemade, and even if they are not, they take more time and care to make. Cotton muslin and almost all other baby blanket materials are cut from a fabric roll, then a border is sewn on and, voila, there's your fancy baby blanket! But it's not as breathable as a knitted blanket.
If breathability is a top concern of yours, we recommend a lightweight knitted baby blanket. Here are our most lightweight knitted breathable baby blankets.
