I'm 4 months old!

I am now 4 months old!! Wasn't that a quick 4 months? I weigh 15 pounds, 3 ounces and am 25 inches long. The 0-3 month clothes have been packed away and the size 2 diapers are on their way. I eat rice cereal and will be starting other solids next week. I coo and babble all the time and readily recognize my mommy and daddy. Rolling over can be added to my list. Sitting up alone will be next real soon. I love to listen to music as well as when my mommy sings to me. My favorite song is "The Farmer and the Dell." I have visited 4 states and already have my passport! Haven't I been busy?!
