Perfect for nap time and bedtime, the igloo projects a peaceful starry sky with twinkling lights on the ceiling, or you can choose the nightlight for a softer glow from the igloo door. This igloo comes with a removable, machine-washable plush penguin that can keep little ones company during the day, then get ready for bedtime by sliding the penguin inside to activate the lights. Customizable controls let you freely choose the sounds, volume, and duration to snuggle into the perfect peaceful environment. Up to 45 minutes of white noise, nature sounds, or soothing lullabies can play while baby falls asleep, and the cry sensor automatically reacts if baby stirs during the night. Sweet dreams! Designed for children over 6 months. Requires 2 AA batteries. Batteries are included for demonstration purposes only. Fresh batteries are recommended for regular use.
