Newborn Pictures?

So We've Decided That We Want To Have Newborn Pictures Done When Our Daughter Makes Her Arrival Come December/January. Well I Have 2 Step Kids, A Girl Who Will Be 3 Years Old And A Boy Who Will Be 10-11 Months Old And We Want Some Done With Them Included. Can Anyone Give Us Some Ideas Or Post Your Pictures? We're Completely Clueless Since It'll Be Winter So No Outside Pictures And I Just Can't Think Of Any Cute Ideas For Siblings.
