So ladies , I need help with my in-laws .

My son is turning 3 years old on April 20 , and my in laws want to plan another party for him . Now I’m not the type that has birthday parties every single year , me personally i don’t like it and don’t want him to get use to that . So his first birthday I wanted to go all out and that’s what I did , but while I was planning his party and getting everything ready , there was arguments between me and the in-laws about what food I wanted there . So I don’t like arguing at all so I let them take care of the food . Now keep in mind they are still mad at me . And then it was the day before my sons birthday , me my mom and my brother were the only ones getting his decorations set up and the in laws didn’t come and help what so ever .they didn’t call or text . So I was very hurt with that , and I knew I didn’t want a other party for him for his 2nd birthday . Now his 2nd birthday comes and the in-laws want to plan something AGAIN. And my and my lovebug talk and I say let’s not have something cause you remember how it was last year and he agreed . So he told his parents we were going to have anything and we wanted to take him to eat or something , and they got mad and said he needed to be celebrated . And I didn’t want to spend tons of money on anything at all I just wanted to take my son to eat . But they kept arguing with us . So his 2nd birthday is here and when we arrived , they didn’t talk to us or anything because we didn’t help out and we didn’t want the party . Oh also I was 8 months pregnant so I was in the worst mood ever cause I couldn’t walk anymore , my feet were swollen , my private area was in pain . So I was in a bitchy mood . But I didn’t show it ! And now my sons 3rd birthday is coming up and they want to celebrate it again !!!!! Omg I told them I just wanted to take him to downtown Disneyland to walk around and take him to eat ! But they said they wanted to celebrate it at kids club ( which is very expensive and not worth it . ) but I’m so stressed out And they want to have a big party for my other sons 1st birthday which is May 21 ! Omg and I don’t want anythinnggggg !!!!!!! Help meeee please ladies !!!
