Feeling like a bad mom 😬

My son turns 2 in April and I keep seeing all these other moms throw parties and stuff for their kids birthdays. I’m honestly DREADING having to plan something out. I hate socializing with other parents from his daycare because they are all so much older than me (I’m only 20 and pregnant with my 2nd). Am I a bad mom if I don’t throw him a party? I just want to do a small celebration with our immediate family and I know he won’t care but just feel like other parents will judge 😫 Idk helppp
