...Both are walking. My SIL was tearing up a bit " oh, they're growing!" ...i pointed out that she should not be proud, she should be terrified, their destructive potential has just increased exponentially.

They both have more teeth in.

Nephew is still wapping his face into things. I told my Bro he should just duct tape a helmet on the child's head.

Niece prefers Blue Buffalo dry, but has had some canned dog food and some kibbles n' bits brand as well...we're collectively doing our best to keep her out of the dog food. Niece also shares cookies with the dogs.

...after changing, niece tried to chew on her ( pee ) diaper. Niece has also slobbered up a cellphone. She does tend to eat things, or at least chew on them, even moreso than Nephew.

Nephew was very enthused when he pushed the chair across the kitchen. He has not figured out how to climb on it...YET. O.O
He is making proto-vrooming noises when handling toy vehicles.

Both are still poor sleepers... :/ and fussy, unfortunately.
