Onsies, overalls, snap in the crotch outfits, duct tape over the tabs of the diaper, anything that keeps the tabs out of her line of vision.
This is not a sign for potty training...even a 10 month old can pull a tab.
This is a sign that she is gaining her finger manipulation skills. She is starting to have much better fine motor skills. This is a good thing that you can encourage with other things, like picking up egg noodles, anything she can't choke on.
She has "learned a new trick" so to speak, cause and effect, she does something and it is fun for her because she gets a reaction.
This is something that all kids this age start doing. It is an almost universal activity.
