There are some things you can do get your little one used to it:
1. Inflate the Otteroo, and let him touch and feel it on land.
2. If he is not opposed to playing with the Otteroo, try to wear it yourself to show him that it can be worn around the neck.
3. Try placing it gently around his neck so he can get used to the feel of having it around his neck on land.
Also, we have noticed that at times, babies are shocked when they are first dipped into the pool because of the colder water temperature – and it’s not so much about the Otteroo. So we strongly suggest that parents acclimate the babies to the pool temperature for a few minutes before putting the Otteroo on; that way they don’t associate Otteroo with the temperature shock.
