Quick question

Why is that when people say they only want one child, there’s always somebody there to say “they’re going to need somebody to play with” or “they need a sibling” like have yall ever stopped to think like maybe there’s a real reason why folks don’t want or NEED anymore children!? There’s obviously a true reason behind why people only want one child! I get so tired of people trying to provoke me into have another child! Like ok! Are you going to watch them!? Are you going to support me on my mental health journey!? Are you going to babysit while I work? People really don’t understand that people can genuinely have a reason for only wanting one kid!
