Five jobs

Pick the app for the job you need done

  1. A sleep log for your public health nurse or GP.All-in-one trackers log feeds, nappies and sleep in one place, and Huckleberry exports your log free.1 Sleep-only apps such as Snug leave feeds and nappies out.
  2. When the next nap should start.Nap predictors work it out from wake windows and the sleep you log. Huckleberry, Baby Tracker and BabyNaps put their nap times on a subscription.11023 No camera, sock or sound machine we read gives a next nap time.
  3. A plan to change how your baby sleeps.Sleep programmes sell a course, a written plan or a chat with a coach. Ask which method a plan uses before you pay, and find it on the methods map.
  4. Watching your baby.Cameras and socks show your baby, and some read breathing or oxygen. The AAP and the Lullaby Trust both say no monitor has been shown to prevent sudden infant death.56
  5. Setting up the room.Sound machines, night lights and sleep clocks set the room for sleep. None of them tracks sleep.

On breathing monitorsThe AAP says not to use a home monitor as a way to lower the risk of sudden infant death. The Lullaby Trust says there is no evidence any monitor prevents it, and some parents find one reassuring. Both say to follow safe sleep advice either way.56

We make Snug. Logging, the timer, the week and a shared log stay free. One payment after a free week keeps the nap times for every phone in your family.
