Here's the site I use for blanket sizes-about half way down page in bold type: http://knitting.about.com/od/knittingskills/a/blanket_sizes.htm. Says standard baby blanket size is 45x60 inches. When I've made baby blankets, I've made them closer to the actual crib size (28x52), because you don't need them to drape over the sides like a regular blanket.
I have made many crib blankets - that is what I called them - they are the blankets that my kids, grandkids, nieces and nephews have drug around!! My mom and I have made a ton of them - my standard size is 45 x 48 inches - it fits in the crib - and it is big enough to lay on a floor for to play on and tuck around a car seat in the car.
