I once had someone in church tell me the reason I couldn't spank is because I had easy children. The children's minister looked at me and we both started laughing hysterically.
I don't have easy children.
But being strong-willed is a WONDERFUL thing!
It shows strength of character and determination, and I would *hate* to squelch that because it can more difficult to parent.
Food allergies and ADHD are difficult to parent. We have our fair share of health problems that make life much more complicated. But it's not about results.
It's about relationship - and people with good relationships work together to get the results of a shared goal.
