You're the boss here! You might have a theme in mind for something different, or you might want formal portraits or casual. I've listed some tips below just as a guideline, but really, there are no rules! Let each individual be unique and true to their personality! Not only will it make for a more fun and relaxed photo shoot, but each of your distinct personalities will be reflected in their portraits forever!
I don’t usually recommend more than one clothing change for toddlers (2 outfits total) as too much fuss with clothing can quickly change their moods! Again, the main thing is to be yourselves and if your choices of clothing don't fall into the above "tips", then that's ok, too!
