Owlet Smart Sock 3 Extension Sock Pack Size 3

Our Extension Pack allows you to continue tracking your child’s heart rate, oxygen level, and sleep trends up to 5 years of age. The included toddler-sized fabric sock works with your existing Sock 3 sensor, and our optimized technology continues to provide accurate readings as your child grows, between 30lbs to 55lbs.

Key Features:

• The Owlet Extension Pack is designed to fit children up to 5 years old or 55 lbs.
• The Owlet Smart Sock is low profile and fits under a regular sock, footie pajamas, or in a swaddle.
• Make sure the Smart Sock is in direct contact with your baby’s foot and properly placed.
