SNOO helps you understand why your baby is crying. Most parents notice that SNOO usually calms fussing within 40-60 seconds. So, if fussing stops quickly as SNOO increases the motion/sound- you can keep your head on the pillow - your baby just needed a little more soothing and is not very hungry. However, if the crying is continuing for more than a minute, you should pick her up to see what she needs. You DO NOT need to wait for the bed to ‘time out’ and stop itself!
