Recent recommendations, based on reputable research, list the range for dietary protein to be from 10-30 grams of protein per kilogram body weight per day.
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.
They are much like a ripple. For a smaller or larger Soft Crochet Chevron Blanket use a multiple of 12 + 3 to create your foundation chain. For example: To make my blanket I am using 6 multiples of 12 + 3 (the extra 3 is for the turning chain.). 12 + 12 + 12 + 12 + 12 + 12 + 3 = 75 chain stitches to start my blanket.
