Just need to vent...

We had our gender reveal yesterday.. My mother didn't want to come in the first place because she isn't fond of my husbands family. A few days before she text me asking to do the firework first (how we announced) before we ate so they can watch & then leave. I told her no. Her & my father came, late at that. (my dad was embarrassed because everyone waited on them to start eating.) So we ate, set off the firework and cut the cake. Right after the cake my parents left. Well after all the festivities were done by husbands father grabbed his camera for pictures of everything and all the family. 
They were posted to social media today and my mom has the nerve to text me pissed off because she didn't get any pictures. I told her YOU LEFT EARLY, but she continued to give me grief. All this but she still insists she'll be the one in the delivery room with me and what not... 
My dad called me not soon after and apologized for her calling me and said he'll take care of it because he knows she's in the wrong. I'm so annoyed I could cry.
