Don't forget to capture those every day moments.  I often photograph my kids very differently then I do yours.  There aren't any elaborate set ups, or perfect lighting, clothes or accessories just my messy house and my messy kids.  And while I LOVE taking portraits in my studio and outside with props and cute poses (you all know I am a sucker for a baby hat or cute backdrop!) Lifestyle sessions are so great too and so real.  I took these photos in about 5 minutes, my house is a mess, my son is in his pj's but I love these photos just as much as the formal portraits we have had taken of our family.  They don't have to be captured by a professional, (though I would love to do a fun lifestyle session with your families :) ) But for now just get out your cameras and shoot.  Shoot from different angles, remember the details, play with the lighting.  I bet these will end up being some of your favorite photos.
