How many children do you have and why?

I am actually planning for 2 children as I feel it is manageable in terms of attention given to individual child and financial planning. Baby no.3 is unplanned, but we also happy to accept the fact that we are going to have 3 kids and I believe it will be another new learning journey for myself to adjust my expectations. I have a few friends who decided to go for 1 child only as they want to give full attention to the kid. However, I think sibling is the best gift that we can give to our child as we will grow old one day.
