It's also a handy food diary for your baby and nursing mom!\n\nYou will be able to make sure that the newborn is getting enough breast milk and to establish the daily baby care. Enter information about food, beverages, medications and supplements you are taking. This will help identify allergic reactions in the infant.\n\nLACTATION\n\nStart the breastfeeding timer with one click! Track the duration of feedings, easily remember which breast you fed the last time: this will help to establish breastfeeding and avoid lactostasis. Record data on pumping and responses to the first complementary foods.\n\nPUMPING\n\nConsider the volume of expressed milk with the option to start the feeding timer separately for each breast or both at the same time.\nKeep records of frozen milk - make sure you have enough stocks in your milk stash\n\nSLEEP\n\nUse a sleep tracker and note down when your child is asleep and awake. Record night and day sleep to understand baby's sleep and wake patterns\n\nDIAPERS\n\nSchedule your diaper change so you know how many diapers you need. Write urination (with volume as needed) and bowel movements separately\n\nHEALTH, FEEDING\n\nMark various symptoms and temperature, enter data on vitamins,  medicines and vaccination. \nRecord complementary feeding data and track the baby's response. Monitor your baby's weight gain and growth. Watch for teething. Erby is great for visiting a pediatrician.\n\nACTIVITIES\n\nRecord bathing and walking, tummy time, games, massage. \n\nSTATISTICS AND HISTORY\n\nView event statistics so you can spot trends and, if necessary, make adjustments to your baby's care. Study your daily routine. A complete history of events, the ability to filter them by type (for example, only walks or pump log) is always at your fingertips.\n\nREMINDERS\n\nSet reminders for the events you need. You will not miss your medication and will not forget to feed or put your child to bed at the right time.\n\nErby is not just a baby development journal, it is a memory of your precious first months with him.\n\nYou can keep a diary for multiple children. Suitable for twins!\n\nOur breast feeding app was created to help even the most sleep-deprived parents keep track of their baby's progress up to one year old by recording daily activities and feeding statistics in this easy-to-use diary.\n\nSUBSCRIPTION INFORMATION\n\nWe offer subscription plans in the app that unlock premium functions of the app:\n- Payment will be charged to iTunes Account at confirmation of purchase\n- Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period\n- Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal\n- Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase\n- Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable\n- Price can depend on location\n\nFor more information please visit the link https://support.apple.com/HT202039\nPrivacy Policy: https://doc.whisperarts.com/policy/erby/ios/\nTerms of Use: https://doc.whisperarts.com/terms/erby/ios/\n\n\nWe are always glad to receive your questions, suggestions and comments.
