Lil brother's life cycles

Summary report of a typical day in the life of lil' brother:

step 1: mean baby (hey! this is kinda fun!)
step 2: mad baby (oh no, you didn't!)
step 3: crazy-get-you-back-baby (Deliverance style)
step 4: sad/grumpy baby (how could the world be so cold and rejecting???)
step 5: silly baby (being sad is BOR-ing!)
step 6: annoying baby (cool! repetition makes my family go beserk!)
step 7: repeat cycle (doesn't everybody love to ride the merry-go-round???)

Of course, his victims are typically trailing a step or two behind. But hey-all in a day's work for lil' man...
