Stages

Sam is pulling himself up to things.  He's definately not on the walk before your a year schedule.  And that is A-okay with me.

He makes me a little nervous though.  

First he gets his hands up and pulls his upper body up.

Then he uses his toes to slowly push himself toward the object.  

In the last month he has cut a lot of teeth and now has all four on top and one on the bottom.

Have you read A Series of Unfortunate Events?

The little sister's main strength is her teeth.  

She hangs off of tables with only her teeth gripping them.

Sam has found his teeth to be a source of strength also.

He bites on AND pushes with his toes for greater strength.

You see why I'm nervous?

I don't see those teeth lasting long if things continue this way.

Especially with all the "love" (see foot to the tush) he gets from his sister.

But he does it.  He pulls himself up to his knees.

And from there it's a breeze.

Until he gets more "love" from his sis.
