Felix the fox is a baby comforter, that becomes your little one's friend at home and on-the-go! Attach Felix to your pacifier, crib, stroller or car seat using its velcro strap. It has a removable sound module that soothes your child by playing 6 different pre-set calming sounds such as mimicking a mum's heartbeat, white noise, nature sounds and 3 kinds of lullabies., After 10 minutes the music shuts off automatically. Optionally, the cry sensor and/or shake sensor will switch on the last played sound if your baby wakes up in the night. The removable sound module is powered by 3x AAA batteries (not included). Once the sound module is removed, you could wash the plush by hand and dry it in the air.
