Stop over-offering and second-guessing yourself…and become a potty pro (or at least better than you were last week!) with this app. Whether you are potty training your toddler or doing elimination communication (EC or infant potty training) with your 0-18 month baby, you need this app! Observation time is key for knowing your little one’s natural timing intervals (how often s/he goes potty) and keeping track of any baby signals (or “peepee dances”) you see. But forget that printable log you got from my website! You can now digitally track how often your baby pees or poops during observation time, or potty training, with ease. If you’ve wondered: “How often does my baby pee or poop?” “When should I offer the potty to my little one?” “If I want to set a potty time reminder on my phone, how long should I set it for?” …The Log is your answer. No more paper printouts and chicken-scratch logging, no more guessing “how often does my little actually pee or poop?”…now you can simply open the app and, starting at either waking or feeding, track how often your baby or toddler goes. Then download a PDF of your results. *You can also take a note of your little one’s signals or other observations by long-pressing the activity button, as you go. After starting potty training, or if you’re doing EC…after a few hours of observation time (or a few days if you’re really inquisitive)…visit the Reports screen to easily see your baby’s intervals in graph or written format. Set a potty time alarm based on your baby’s actual timing intervals, so your smart phone can remind you throughout the day when to offer a “pottytunity” - or chance to go potty. If you have a toddler you’re potty training or wrapping up EC with, you can use this app to set an alarm based on your observations - welcome to your new potty training alarm app! Track one or more babies, keep the logs separate, and easily re-set the data to start a new observation sesh any time (I recommend you re-log your child’s rhythms every few months or so to keep it fresh!). Stop over-offering and second-guessing yourself…and become a potty pro (or at least better than you were last week!) with this app. Developed by me, Andrea Olson, author of Go Diaper Free and The Tiny Potty Training Book, whose 5 children were all out of diapers by walking, none requiring potty trained…a mom who has hardly had to change a poopy diaper and has saved over $10,000 in diapers across their babyhoods…you’re in good hands when it comes to observing your baby for elimination communication. Learn more at godiaperfree.com or via the app, itself. PS - if you’re stinking at potty training, learn more with the free classes inside the app. If you don’t know what EC is, it’s the natural alternative to diaper dependence and potty training, and it starts as early as birth to 18 months. It’s what people have done for all of human history, long before diapers were invented. We also have a free class and books on that.
