I'm terrified.

So within the past week 2 people I know (1 I'm very close with) have lost their babies. One was my work friend who lost triplets at 23 weeks gestation. The other is a friend from high school that I haven't seen in years but still had on Facebook. She lost her son at almost 5 months with no explanation. Just went to his room and he wasn't breathing. I have a 4 month old and now I'm a wreck. All I can think about is something happening. I can't sleep. I just keep checking to make sure she's still breathing. 😔
