photoshoot coming up!

Alysia
I have my announcement photoshoot on Thursday. Anyone have any ideas on what kind of pictures we should get done? 
I'm currently 12 weeks pregnant with my third, already have 1 boy and 1 girl. We're avid fishers
What about outfits? The kids and fiancé all have brand new black shoes, not "fancy" more sneaker, sporty looking. So hoping something more casual but I find outfits the hardest part.
Any ideas help. Thanks in advance
