Tattoo for a Mom with twin boys

I'm looking for a tattoo that I can get that symbolizes me having my twin boys. Can anyone help? I can't think of a thing. Thanks.

I am at a lose also, was thinking about doing a pair of tribal sharks cause when they first started getting around they swarmed you but now that they are older, turning 3 in Jan, I have to figure something else and having a hard time coming up with something perfect that represents them.
