Kam uses this ALL the time. Many times use it for under his feet if he’s sitting. Because he doesn’t lIke to keep his feet on it when it’s vibrating, teaches him to respond by bringing his legs up and down.
If Kam is in the Boppy or in his stroller I put it underneath so he can feel the vibration and feel his body.
If Kam is in his Stander I put it under the Boppy and the Boppy under Kam’s forearms while he is in there.
There are to level modes. When batteries are fresh even the low mode is strong. You’ll need rechargeable batteries if you keep the vibration on.
You have the option to have it’s an adjusted toy and use the micro switch with it. That’s the one we have. I regret that because we never use at as an adjusted toy. So we just keep the micro switch pushed so the vibrator stays on.
