Julie, I feel the same way too. But now that my son is taller than my husband, who knows, one day when I'm old, he might be tucking me into bed.
hue, I don't think Cactus Hotel by Brenda Guiberson would fit what you're looking for but it's worth a look. One of my favorite PBs. Nonfiction.
Farfallina and Marcel by Holly Keller is a lovely fiction PB about friendship as the two grow up and change.
There must be more!
