re: How much dI'd your second child cost?

How old is your first child? Things like diapers, food/formula, clothes, wipes, etc, haven't gone up that much in the last few years. If anything, there seems to be more generic options available these days.

If you have same gender for second kid and kept all the stuff from first kid, obvously you can reuse all that.

Car seats can be used for up to 5 years from date of purchase before they "expire"

Depending upon your current kid's age and bedroom stuff, you may need to buy someone a new bedroom set.

Childcare facilities will usually give you a slight multi-child discount. Maybe 5-10 percent. But remember the baby room is the most expensive room at a child care. When we lived in Katy, we used A Child's Reflection who was amazing and I think multiple kids got you 5 percent off the cheapest tuition (this was over 4 years ago).

The biggest thing for us (ours are two girls, three years apart) was the cost of prenatal care and childbirth. When we had our oldest, my wife's insurance was a good plan, we paid $50 flat fee for the entire prenatal stuff. We paid a flat $1500 for the entire hospital stay for childbirth, including mom and child.

By the time second kid came around, her insurance had been forced to switch to a high deducible plan. Total costs were closer to $6,000 for both prenatal and hospital care.
