Lass,
She's not necessarily fussy, though she fusses more than my other two did; she is a climber! She is up on the kitchen counters, the stove (yeah I know), the washer and dryer, the toilet, etc etc.
It's hard to keep up with her and it would be extremely frustrating unless you've recently had a kid like that and are used to it.

The other day I was getting clothes out of the dryer and heard breaking glass. She was up on the counters, throwing dishes out of the cabinets. Oy!
