I would suggest NOT sending out second packages. Just give the P O extra time to deliver. These are not normal times, for whatever reason.
I had to send back someone's second shipment to me, once the original one showed up, and it was an unnecessary expense on postage. Just be patient....
Hope everyone is having a good week. My heart feels heavy for what is going on worldwide and in our country too. Sewing is a great thing to focus on, especially sewing for someone in need.
