My son is only six months but I can relate to getting stares and comments. How dare that woman! You just keep doing what you're doing. Screaming children are, in fact, a part of life. Now if you have this problem when he gets much older, then I would address some issues. But right now, you're doing a great job. Don't worry about the outrageous comments of other people. I seriously doubt her children, if she has any, are perfect angels all the time. And screaming 3 times in public. People will just have to learn to get over it! I hate to hear a screaming baby as much as the next person, but who am I to judge the parent for a child doing what children do.
Here's what happened to me. Maybe you can relate. I took my son to Sam's when my mother came up for a visit. It was around his lunch time and he got hungry and fussy. (He acts like he's starving to death if I don't feed him on time) So I sat down on one of the display tables of outdoor furniture. It took me a few minutes to get his bottle ready and an older man looked at me and said, "I can't believe you would bring a screaming baby out in public." I've never been one to know when to keep my mouth shut so I said, "well sir, he's hungry and he has no other way of telling but to cry. And if you don't like it, you can leave. Don't let the door hit you in the butt on your way out." So he left and then I was so upset that I sat there, feeding my son, whimpering like an idiot. I refuse to made to feel that way any more. It's not our fault our children can't tell us what they want or need.
You keep doing what you're doing. You're doing a GREAT job, MOM!
