Trixie Tracker offers a simple online application for parents to keep track of their baby's various activities. While this may sound a little obsessive, I would have to say it may help parents to organize their baby's lives. Trixie Tracker aims to help parents keep better tabs on the various activities surrounding a baby so that they have a record to analyze and gain a better understanding of their baby's habits.
Trixie Tracker, which logged its 100,000 nap in 2006, is organized with a number of tabs with each set up for a different tracking category. The tracking categories are sleep, diapers, bottles, solids, nursing, pumping and medicine. Trixie Tracker is currently offering a free 2 week trial and then is $14.95 for 3 months billing periods or $8 per month if you go month to month. The current logged numbers are shown in the image below.
I do not expect to use this site anytime in the near future, as I do not have a baby, but a colleague of mine is preparing for twins so this might be the web's gift to him and others expecting an arrival soon.
