Welcome aboard CF, JuJee,
Your best bet will be to
discuss it with his pediatrician.
Next best, try spending the night on the
boat, perhaps he will accommodate overnight.
Finally, slow the
boat down, so that the motion is more gradual, help him be comfortable.
You can use the CF Custom
Google Search (under the Search button) to find a number of links about preventing seasickness. Most of them are aimed at adults. However, the wrist bands, and preserved ginger should be safe for all
kids, barring a ginger allergy. Ginger tea, made from fresh ginger root (about an inch of thinly sliced ginger root to 1 qt.
water, steeped 5 min., may help quite a lot). It can be re-heated.
To some extent,
learning to cope with motion is a skill. Looking at the horizon, keeping your ears parallel to it, often works wonders. If he gets sleepy, let him sleep.
