would you be upset?

My husband and I both work. Today while we were at work his mom went to the babysitter and picked up our daughter and took her to see the Easter bunny for the first time. I went to pick her up today and got a text saying his mom got her and took her. I'm pisssed. Idk if I should be but being a working mom I'm sure I'm going to miss enough firsts that I can't control. I want to be there for all of them that I can. Now part of me says that my daughter won't remember so what does it matter. But I remember. His mom could have at least asked me first. I would have at least packed a cute outfit like the 2 Easter ones we have already. 
Sorry for the rant but I'm mad. Would you be?
