## Description

Love your Dream Sock for longer, 18 months-5 years

Review: super - me encanta
Review: Life saver! - I used this the whole first year of my babies life and I slept so well at night knowing I would be alerted if his oxygen levels went down, or heart rate. I was so worried about SIDS and this gave me peace of mind. It’s a little pricey but it’s worth every penny if you’re a worry wort or a helicopter parent, you will not regret this purchase! Very durable as well! The slipper is washable!

## Questions & Answers

**Q: Dose this work with Owlet sock 3?**
A: Only works with the smart sock 3 (3rd generation) since the smart sock 2 has a different smart sock design and different base station designs, so the socks won’t fit the sensor nor the base station charger as how it’s been redesigned. Hope this helps!

My daughter has worn this sock since she was an infant. She will not go to bed without it now. This extender sock allows her to grow and still give us the assurance that she is safe every night.
