We’ve talked about our favorite socks on here before (find them, here!) but (in our opinion) the smallest size is still a bit too big to stay on newborn piggies! So for newborns, THESE socks are our #1 pick!!! They have an elastic closure, are made of organic cotton, they are so soft and come in tons of colors! I had this exact pack when my boy was teeny tiny and absolutely loved them!
