I mean 'high-need' as defined by Dr. Sears (http://www.askdrsears.com/html/5/t050400.asp). High spirited is also another term for 'high-need' kids. I have a 'high-need' son and it scares me a bit to try for a second baby. I'm afraid I would feel just totally overwhelmed with an infant and a toddler who constantly needs my attention. My husband and I were originally planning on trying for a 2nd child when our son is 18 months old.
