We open this but our baby never used it because even when he is sleeping his pacifier have to stay in his mouth. he doesn’t hold it for a long time in his mouth. so my husband did not want to wake up every second during the night to put it inside his mouth; he just sleep in our bed so every second he push it out it just faster to put it back in his mouth before he wakes up 😂😂😂😂. Now you know a little bit about our baby😁. Please only ask if you are interested and you can pick it up someday if you want. thank you.
