women who complain that already have a kid

It gets on my nerves so much to see these moms on here whining because they have been TTC for 3 months and they are so sad and they want to give up when they already have 1-3 kids. I'm not saying it isn't sad, but seriously? Be happy about the kids you do have not all of us have that! 
Rant over 
I'm sure someone will be rude 
I'm just so annoyed.
