Hi,
Most expectant parents will have made sure that they have all the other essentials such as the furniture for the baby's nursery and the stroller. Although these are great gifts to be able to give not many people can afford to. Besides, these types of items are usually the prerogative of the new parents and so are not really ideal. If the couple are expecting their first baby it makes much more sense that your gift include the essentials since sometimes they might not know what these are and could find themselves without them just when they need them the most.
