Miss Manners: My daughter scolded me for offering to help with her baby shower

Dear Miss Manners: I was delighted to be invited to a baby shower for my daughter, hosted by two of her friends. I thanked them for their generosity and asked if I could bring anything. I also asked if they would like photos of my daughter as a baby. They said yes to the photos, so I sent five pictures (no naked or embarrassing ones) and thought no more of it.
