When you're a couple - people ask when the patter of tiny feet will be happening (because you can't be childless surely?)
When you have one child, people ask when the next one's due (because you surely don't want an only child?)
When you already have 2 children, and they are both the same sex, you get asked if you're going to try for the boy/girl you don't have (because having the same sex children obviously makes you desperate for the gender you don't have)
When you already have a boy and a girl, and you get pregnant again, people ask if it's an accident (because why are you trying for more when you already have what you're supposed to have. The magical boy/girl - 2 children - that's it!)
People are rude. They don't for one moment consider infertility problems, miscarriage, stillbirth. They ask about age gaps (oo, that's big, or oh that's very close!) There is an opinion on everything.
OP - I am so happy that you have your DS, and wish you all the very best with your second. I'm so sorry I have no advice on the all consuming bit, as I am a complete all consuming nightmare when it comes to TTC, and relaxing isn't easy.
Wishing you all the best and hope it's a BFP soon
