Annoyance with genders

The next person that tell me my baby needs to be a girl or tells me I better be having a girl is getting their teeth punched in.

But in all seriousness why does it matter what gender my baby is? Why does everyone think you have to have a boy and a girl and then be done? We have a boy but we want a big family so even if this one isn't a girl it doesn't matter to us. Also my mom was so mentally and verbally abusive to me I'm terrified to have a daughter I could see us having 4 -5 boys. All we just want relatively healthy babies.
