1 Don't buy two of everything
When you find out you've got two buns in the oven, the first thought that goes through your mind is ... well, let me skip the first thought. The second thought, however, usually is that you are going to need double of everything. Not the case.
Yes, you will need double the diapers, wipes, bottles and other necessities, but do you really need two swings and two play mats? Chances are you can have one baby in a swing and one on the play mat. If you do feel the need to double up on something, look to your friends and neighbors. It can save you money you'll need to spend on double the diapers and wipes.
