yup, I'm watching my friend's 3 year old today while she's away for a huge doc appointment, and trust me he and my 2 are getting along great for the most part except that he insists on scaring my 3 year old with lion sounds and then running after her and trying to fall on her. At first she just wept but I just saw her yelling at him "don't taach me. I will tell yo mammie that you hot (hurt) me!"
Oh my god, the poor kid was shocked. Now he's playing gently.
Sara is a smart one.
:D
