Can the mould from a swimsuit kill a baby?

I went swimming about a month and a half ago, and afterwards I got distracted and left my swimsuit and towel bag in a locker (with a little ventilation, but not much). I went back today and found that the swimsuit had some mould on, and as it didn't fit me anymore anyway, I threw it away immediately. However, the bag didn't have very much on, so I went to the sink and tried to wash it off (fairly successfully). However, after that I went down to my library (without the bag) and borrowed some books. I was in there for about 45 minutes, and I am worried that I may have transferred mould spores to the librarian, who has a 8 month old baby. Please, could someone tell me what I should do/how likely/dangerous this is?
