I'd say I normally get about 3 months notice from a mommy for newborn pictures. I've had some regular clients email me right at 12 weeks, I think. You know who you are!! This lovely little baby's mommy was probably the shortest notice I've ever gotten. Luckily, I had a cancellation and was able to photograph her about 5 days after her mama emailed me. Gosh, it was all a blur. Even the session. Her dad was doing dishes. Her mama was chatting with an aunt. It was so relaxed and quiet. There was a John Wayne movie on the tv. I'm not even sure it all even happened. From the first email to the actual session it all happened so fast. Good thing I have some pics as proof.
P.S. Please don't be disappointed if I can't get you in five days later. For reals, I just happened to have a cancellation. Technically, I have no open sessions until March. I have 4 mamas on my baby watch list right now!
