I have 2 boys, ages 2 and 4. Since my oldest was a year old I've used the same blankets. They are made by Circo and sell at Target for $4.99. Yep, that's it. They are fleece, lightweight yet warm, are easily washable, are VERY soft, and most important, they are durable through the lives of little boys. They use(d) them in the crib, in the bed, carrying them around the house, at preschool, in the car, and on trips in the pack-and-play. They are in the baby section (as opposed to the regular bedding section in the store) and are usually found on an endcap. We own 6 of them that we've had between 3 months (just bought another in August!) and 3 years. I've owned a hundred baby blankets between the two of them and they are the best. And for $5, who can beat that? Geez, I'm a commercial!
