needing advice

my female pig just had babies last nite and i found them this morning. im worried about the tempeture outside. i live in florida and it was 50 degrees when i found them. i put 2 big blankets in the pen with hay on top. she has her babies on top of blanket and she is laying down. the babies are wondering around so i put with her and they are ok so far. should i do anything else? any advice would be greatly appreciated! im new at this pig farming!
