What's the worst experience you've ever had with a baby?

I stayed with my parents 2 weeks after he was born for I did not have to be alone while my husband was at work. My mom helped me out a lot with taking care of him for I could rest. My first day on my own in my house. I was changing his diaper and he peed on me all over the floor. I then went to clean him up and then he pooped it went all over, I had it on my face and all over our new white carpet. I cleaned him and myself up, and then called my mom crying thinking that there was something wrong with him, I did not know that they could shoot poo that far. Other then that the worst thing that happened was after my husband left for work I went to check on my son who was 2 months old, he would not wake up fully and when I took his temp he was 105.9. I called my DR right away and they told me not to worry just put him in a cold bath, I freaked out and called my mom she told me to take him to the ER right away, they had to give him a shot and an IV.
