As the parent of a now 3 year old who needed constant movement to until she learned to walk (and afterwords provided it for herself- even now she is in constant motion), cried constantly, was uber sensitive to others' emotions/moods, refuses to wear anything that is "not soft"...yada yada yada....Yep, I believe in the high needs/ spirited child. I don't feel it's a diagnosis, though, as if something is wrong with her. I just think she's a lot like her mom- very passionate, opinionated, energetic, sensitive, and persistent. I use the "label" as a way to find help in guiding her to use those qualities positively, to get help from others whose kids have similar qualities, and yes, occasionally to get sympathy when she has utterly worn me out. Her brother is a much easier kids to parent, so I know it's not just my incompetence.
And I had to laugh at the choice, "My kids are easy because I practice AP. " HA!!!! AP is NOT a recipe for an easy kid. In fact, my choice to practice Attachment Parenting with my kids probably made parenting my "high needs" girl just that much more difficult when she was small. I mean, if I'd let her cry it out about her myriad extra needs, she may have given up on them and my life might have been simpler. But I value her strength and determination, and I think all that extra effort to value her needs however inconvenient they were/are is totally worth it to let her maintain that extra "verve" that will serve her so well.
So, maybe I wanted to see a choice that said, "congratulations! your child has a MASSIVE amount of potential!"
