Isabella did the same thing for a while and she even looked for ours (or anyone's) when I realized she was giving it too much attention I completely ignored the situation and I put her always in bodysuit so she couldn't put her finger directly to her skin, and it was much better, sometimes when she doesn't has a bodysuit she pulls up her t shirt and shows her tummy but I try not to encourage it and after a while she forgets about it.
