He's 11 months. Just not sure whether I'm BU to be irritated. I say it sometimes obviously in conversation so I'm not a Brian Sewell-type stickler for perfection when it comes to spoken English.... but should we not be teaching correct words first as he will pick up enough slang on his own anyway?
One of the grandparents is always doing this - asking DS to pass her a book or a toy and repeatedly saying "ta, ta" at him. I tried the subtle approach of joining in and saying "thank you DS" but she didn't click and kept on with the "ta, ta, ta." Not sure if I should correct gently or let it go?
