I only have the one DS, he turned 3 last month.
Still haven't had that urge that I must have another child. We were thinking of TTC later this year, but it's really not solid.
I'm 34 years old, my DH is 42. My first and only pregnancy was complicated and resulted in DS being delivered at 31+2. Having a premmie was quite a rollercoaster.
DS is a real firecracker, very strong willed and incredibly active. He has a speech delay and is currently in an early intervention play group. The fact that he isn't an 'easy' child just makes me want to focus on him more without bringing another baby into the mix.
We could very well end up with an only child, and I think we'll both be fine with that
