So mommas I need advice.. I set violets first party date on Saturday July 22nd at my church outdoor shelter..the pastor just informed me that a family reserved that date last year and they forgot to transfer it to the new year calendar so I'm upset cause I already sent out the invites and it was her actual birthday plus it was on a Saturday 😞so I then switched it to the Saturday before which is the 15th.. then I had to call the bounce house people and reschedule her professional photos then I texted and fb messaged all the guests which was some of my close family, close family to Spencer (baby daddy & bae) and some of my friends with kids..so my MIL texted me that there having a beer party that day..I told her the situation and how I can't reschedule again. we got in this BIG over text argument with her assuming I planned it without asking them and how I always put my family first blah blah blah but I actually did everyone within a hour so she then went into calling me a possessive mother and I'm a selfish little girl!! I checked that bitch real quick, anyway long story short should I reschedule again again to have them come or keep it as is and if they chose to go there beer party instead of there granddaughters first birthday, they will regret it and there done. So ladies I need honest opinions and I don't have screen shots of the convos if needed..
