The first tweet was a call to pray for her son and came a few minutes after she called 999.
If she has 5000 followers maybe she was thinking that could lead to 5000 prayers for her son.
I don't believe that's going to do **** to help, but obviously some people (perhaps the majority?) think prayers can help in these situations or they wouldn't ask for them when things like this happen.
I don't know the entirety of what she posted, but according to the article:
That was the first tweet after the accident.As paramedics tried to revive him, Ross, who used the online name ‘Military-Mom’, posted the note: ‘Please pray like never before, my 2 yr old fell in the pool.’
Well what else could she do? The paramedics are already there, so she's doing the only thing she can think of that may actually help her child, call for people to pray for his/her safety.
I see nothing at all wrong with that. I don't agree that these prayers were going to do anything, but to attack this woman for doing what she obviously thought might help her child is sick in it's own way.
Now, if she had been tweeting about her shoes or something, the outrage would make sense. But outrage over tweeting for prayers for her child?!?!?!?
