Thank you.
I had my child later in life, mid 30s, so I've been on both sides of the fence.
I've asked the question. I hope I wasn't bullying about it, I certainly never intended to.
And I was always super annoyed when people asked me that when I was younger.
After I had my daughter, it was always "when are you going to have another?" and it was ALWAYS with the air of an only child grows up selfish and unable to bond because they never had anyone to connect to and share with.
