Many heads better than one
Upset, teething baby with apparent earache.
Me: "She's also falling over a lot, which isn't helping. Keeps bumping her head."
Zara: "Yes well, her balance will be affected, won't it? If her ears are blocked up."
Me: "....... Ohhh yes, so it will!"
Five children and nearly 40 years on this planet and it hadn't occurred to me to make that connection at all! Duh. *Rolls eyes @ self*
