I brought my 3 yr. old to the playground today and there was an older women...maybe a young grandmother, who kept talking to my son and his friend. At first I thought my son's friend knew her because she was talking to him so much. She was sitting right in the middle of where my son and friend were playing. It's one thing for someone else to make small talk to kids at a playground but she just kept going and going. At one point she had said Hey little boy how old are you and what's your name! It wasn't exactly what she said but the way she said it that really bothered me and got me thinking about talking to my son about strangers. I don't want to scare him but definitely want him to be more aware. He starts preschool this fall and I'm so nervous about him being around new people. This will be the first time he'll be away from me. Any books recommendations would also be great!
