There is no way you will be able to do that on Priceline. They only guarantee two people... and you are not even guaranteed two beds. So, I do not see how you can use Priceline for this purpose.
Now Hotwire will allow you to say two adults and two children (ages 2 - 17) in a room. But you would still need to find a way to accomodate the baby. I have never personally tried booking four into a single room... guessing you would get two beds in that case.
So, Priceline is probably out... but Hotwire could work... just make sure you are clear up front and put in two adults and two kids. Hopefully, having the baby will not be a problem.
