Nanit will disconnect and not reconnect, automatically. If my baby turns to his side, nanit won't be able to find the band until the baby moves again, which could be 10 minutes or longer. Sometimes it will time out and stop monitoring all-together, even though the band is in plain view. Nanit will also force updates, so if you happen to check on the baby multiple times a night, it may force an update, so you're baby will be without monitoring at 3 AM or whenever the forced update comes up.Likewise, Nanit can disconnect and will be off all night without ample warning, even when the band is in full view, and it cannot automatically reconnect by itself. This can be frustrating, especially if/when internet goes down and the "local" network doesn't work right, and when my child covers the band from the camera's view by raising his legs in his woolino sleep sack and the camera can't read anything and thinks the baby was taken from the crib so it turns off and monitoring cannot begin until someone manually begins it, again. Personally, I would only recommend nanit for children over a year who are less at risk for SIDs. For infants, I def feel much better using the Owlet, which monitors constantly and was for me, much more reliable than nanit.
