Ditto Julia M.
*Also, you cannot expect HER to stop cussing/swearing, if everyone else around her is still doing that. Its hypocritical.
I notice you are a young parent... so please heed to the advice all these long time Mamas on MamaSource will tell you.
My advice is: The way you get her to stop... is by NOT having cussing people in her environment AND you make it a RULE... that around your CHILD... there is to be censored language.
Next, you do NOT "scold" your daughter... she is ONLY 11 months old and they don't even know the formal definitions of these words yet. Like Julia said, they are being a "copy cat" and repeating what they hear. That is what children do....
You best monitor her environment closely... because, if it continues, your daughter will get older and the problem will most likely get worse. AND, in tandem with this... she will ALSO "copy" the behavior and habits of what goes along with the cuss words. And it ain't a pretty sight.
I've seen grade school kids like that... and it really ain't "cute" or innocent by that age.
Now... do you want a little girl to be that way, or to act like that at such a young age, and to act that way once she starts school or starts to have her own friends? Think long term.... I don't think you'd want a little child, "copying" these sorts of behaviors, from Adults.
As my daughter's Teacher once said "Some kids, because of their environment, are not kids anymore... they are so young but they don't have little child hearts or souls anymore... they have been exposed to too much already that is NOT age appropriate.... and its hard to turn back the clock and re-teach them basic, innocent, child thinking...."
REALLY stop all that cussing in your baby's environment. She is only a baby... much too young to be exposed to all that.
As she gets older, you don't want to have any 'regrets' about how you raised her.... nor do you want your daughter to have behavioral problems later... because of it all.
The book "What To Expect The First Year" is really good. You can get it from www.amazon.com or any book store.
Protecting a child from "harm" also means their environment, language used, behaviors displayed in front of them and from Parents, and EVERYTHING. Babies and kids absorb and get affected by EVERYTHING we expose them to... for better or for worse.
All the best,
