This blanket is great for the 4 month plus crowd. I would not recommend it for under 4 months. My two love to rub the tags. My 5 month old likes to study each one so it's nice they are all different. These come in two sizes and I would recommend the larger one. It is just big enough to cover my 5 month old in his carrier. My 2 yr old loves to put it over her lap in the car so it is a great travel blanket because it doesn't take up much space. Since it is not big enough to swaddle your baby, I would keep a close eye on babies younger than a year so they don't accidentally pull it over their face. This is really what I would call a "soothing toy" and I wouldn't put my under 1 yr old to bed with it.
