Purchases For Baby

Yesterday I purchased 5 new Organic Cotton Singlets from Target. They were 20% off so I made a saving. After doing some investigating I think I will return one or two of the singlets, even though I have read that it is easier to have more than you need. I would rather buy some extra things that I need after the baby is born because then I won't be wasting resources. The baby will grow out of this size (000) approximately by 3-4 months, so I have read and I would rather not get too many things for the baby.
