There is no law saying you are required to buy gifts and be extravagant as a hostess. There is no award or medal for doing so. Try to see this then that you have no obligations.

Must it be you who hosts a shin-dig? Might you suggest going there instead? How far away is this baby and family? Are you able to make the visit a day trip? You might have to end up giving up some of your alone time but be the one to dictate in what manner that will be.
