You may want to look into SODA (Sibling of Deaf Adults) activities for your son. Many Deaf camps allow hearing siblings or perhaps a specific SODA/CODA/KODA (Child of Deaf Adult/Kid of Deaf Adult) social event. He may feel like it is less "weird" (if that is the issue) if he can connect with peers going through the same experience.
my mother was irritated, why ? her neigbour kid has heart problem, i have heraring problem...i think she will one who constantly worry about her kid. i´m perfectly fine...exept hearing.
children are individual beeings, everyone need different time. it´s only important to give attention to their children, and a lot of love!
