My dp and I have one child. He's turning 2 in April, and we've had the chat about potential having another. Tbh it's not a massive priority in our life right now to have another child but I've constantly got this niggle in my head that he needs to have a sibling. People tend to say, "An only child is a lonely child" and "you need to have them close in age" I don't believe in these sayings and comments but I would hate to think he's grown up with no siblings if we were fortunate enough to have another child, but it wouldn't be the end of the world if we chose not to but am I being selfish? Should he have a sibling? Will he be lonely? Will he have all this responsibility when we are old and grey?
