Took 15 month old to hospital to see grandpa?

My great grandpa is deathly ill (nothing contagious) but when I got there I started thinking about how dirty hospitals are and freaked out about everything he did and touched. My grandpa isn't expected to live for much longer and I drove 2 hours to see him. I also didn't have anyone to watch him while I was in there. Am I freaking out for nothing and would you have done the same thing? I could have waited to come up till someone could watch him but I was scared I wouldnt make it in time.
