If you have a child coming up, then it should be reasonably obvious who the mother is. Unless you are a surrogate, having the child come out of you pretty much means that it is yours. However, a DNA paternity test is pretty much essential to figuring out who the baby's father is. While the law generally grants legal fatherhood to your husband, if you have not been married in at least 300 days (or have filled out an Acknowledgment of Paternity form), the baby will not legally have a father on its birth certificate. As this can be a very big deal for the child, making sure the identity of the father is known is a high priority. A home paternity test may be your best bet.
While there are a large number of different types of paternity tests available to you, these can often be very expensive. Using a reputable lab for your testing, you can easily spend between $400 and $2,000. Yes, determining whether or not a particular man is your baby's father can be as expensive as buying a used car. Thus, finding out your child's father can be both dangerous to the baby (as some kinds of intrauterine tests can end up being), and somewhat financially dangerous to you (if you happen to value all of those luxuries like eating).
Honestly, if you were rich enough to be able to drop $2,000 on a paternity test that is professionally done in a lab setting, you could probably afford to raise your child without having to rely on some man. If you aren't quite as rich as Madonna is, you can still find out who your child will some day want to ask the difficult questions (think "why don't you live with us?"). You can use a home paternity test, and solve a lot of the little mysteries in your child's life.
The biggest up side to a home paternity test is not just the fact that it is relatively inexpensive (averaging around $200 a pop). While that is great, cheapness alone is not that great.
The really great thing about a diy paternity test is that it can be done in your own home, where you can have some privacy. There can be a lot of emotions involved, including embarrassment or even outright shame. With a diy paternity test that you can simply mail off and get the results to, the whole event becomes very discreet.
