mil has possible staff infection can she still babysit?


my husband and I have a work event and we typically have my parents babysit but they'll be out of town for a birthday party so our plan b is my in laws. my mil recently had surgery to remove some pins from her leg and its been oozing and is possibly a staff infection. she can't get up and move around so my fil will most likely be taking care of him most of the night but is it safe for a 4 month old to be around a possible infection? any input or information would be appreciated thank you
