Hello, I am TTC baby #1 and it might be my first and last as I'm not sure I would want or could handle 2. Guess you can't say until you've had 1! I'm not very close to my family and only know a couple of people who have young children. I am worried that if I have just one then they will be lonely without a sibling and hardly any close family. On the other hand I don't want two just so they don't get lonely. Can anyone else relate? How did/do you keep an only child from being lonely and bored?
