I have no idea, DS is my PLB aged 19m.
Basically you know the phrase "he's into everything" - DS just takes it to an extreme. We go to a baby group (baby signing which I know some people are
about but it's really helping his speech catch up) and he's always the only one who doesn't sit still contentedly with mummy. He's always opening the door and escaping into other rooms, exploring everything (he's like it at home too) and screams if I stop him.
I don't know it sounds really daft written down but it's getting to me (if it weren't for the usefulness of the signing I would've given up the class by now) - from the reactions of all the other mums with their perfect sedate babies/toddlers, my DS is misbehaving :(
Which is ridiculous thing to think of a 19mo isn't it - babies can't be 'naughty'! but that's the reaction I get.
My DD was quite a curious girl but she always got the "ooh she's into everything isn't she!" - as a compliment rather than an insult 
I don't get it. Am I doing something wrong? :(
