My husband & I got family photos taken last Oct. with our then 3 yr. old twins. (*TWO* 3 yr olds!) We had seen some pictures Tanya had taken for friends and loved them so we gave her a shot.
First off, she's very flexible with her schedule (ie: understands napping kids do not need to be awakened). Also, she's knowledgeable about what time of day to take the photos, which angles to use, what colors to wear (ie: don't wear black or white for black & white photos). She comes up with neat places to take the pictures (ie: Woodland park, the beach at Carkeek Park - where we did ours, etc.). And what I found most important, she is patient, patient, patient with the kids (our shoot took nearly 2 hrs. and she let us be completely in control of how long we wanted to stay, let us take breaks, etc.).
Now to the final product. Her pictures are gorgeous. She takes beautiful candids, color, b&w and the prices are SO affordable. (She quotes per job, so I can't give you a figure.)
The only, only, only downside, which was TOTALLY my fault, is that I told her we wanted "family pictures" and didn't make it clear that I wanted more candids of the kids with my husband & I. Most of the ones with all of us are posed shots. She definitely would have accommodated me, so be sure to tell her exactly what you're wanting.
All in all, I think Tanya is wonderful for family pictures with kids, her prices are right and you will get many pictures (you get to keep the proofs.) Check out her website for some samples.
Good luck & have fun!
