The full note reads:

"Samantha has been playing roughly and aggressively with the other babies; they will be crying and upset but she is smiling and enjoying herself — even our using firm voices to tell her it’s not OK to hurt her friends and remove her from area, she is smiling and going right back. Can you help us out by maybe discouraging her to not play roughly with her friends and her dog.

Now, I don't have any kids and I'm quite sure that I'm not a genius, but I'm PRETTY sure that THIS IS WHAT BABIES DO! I mean, discourage your baby for smiling and crawling over to the other babies? Give me a break.
