Bodhi sitting up & laughing up a storm

We have been practicing the delicate art of balance. Bodhi usually prefers to stand but we've been trying to coax him into sitting upright by himself, and it's going pretty well. Sometimes when he's reaching for something he tips over, but don't we all! We've (actually I've) been trying to see if his hair will spike up on the top. I brush it back after a bath and it sometimes stays. Two women today remarked about his "red" hair... we'll see. At least it will be spikey red hair!!He's also been wildly entertained by simple things lately. I have been saying "Booooom" and he laughs histerically. He also likes it when I farting noises with my mouth. Sometimes I forget and do it at work although I don't get the same reaction from my co-workers...
