I am 24.5 weeks pregnant with twins. I have an almost 2 year old ds at home. I just purchased a second safe seat and after much consideration, a Valco double with toddler seat. Even though I already have one child, there is still a lot I need to buy - Double snap n go, snuzzlers, sheets, miracle blankets, new bottles, etc. When should I start buying/ordering stuff? Thanks in advance.
