I've passed the stage of tracking dirty diapers, feedings and baby milestones, but this new website would have come in handy. Bobohelper was recently introduced as a free website for parents to track everything from baby firsts, to doctor's visits and vaccinations, to breastfeeding (was it the left one last time, or the right?). Log in, and online charts let you track it all in one place.
There's also a shopping section, with one-stop shopping by sale, coupon, store or brand. And of course, message board to connect with other new parents.
Try out Bobohelper and let me know what you think!
