Toddler with flu

Jocelynn
I'm 3 days out from the due date and my SO wants to bring his 3 year old to the house to stay with us for while. I'm overjoyed BUT he has the flu  since Friday. My SO and I had our shots a long time ago, but can I still catch it from his son??? I'm a little apprehensive about having little man here while he's still trying to get over the flu. What should I do??
