(Memphis) Couples trying to have a baby want to make sure they have a little money in the bank.
A new study finds the average cost of having a baby in the U.S. is $21,000!
The cost of having twins skyrockets to $105,000.
Pregnancies with triplets or more cost nearly 20 times as much.
Pennsylvania researchers found bills add up because women with twins or more may have more pre-existing conditions and hospital stays are usually longer.
