Kid friendly beaches

I have a 18 month old and loves to play in the sand and water. Any ideas on some kid friendly beaches with calm waves.

Thanks

One more thing, we will be there mid October.

Kuhio Beach in Waikiki has a breakwall that makes the area pretty safe.

Hanauma Bay is usually calm.

Ko %26#39;Olina Lagoons are safe.

Most of Ala Moana Beach is fairly safe.

Kailua Beach. My grandkids have been playing in those waters since they were less than a year old.

My daughter and I thank you for your suggestions. I did some research and Lanikai and Kailua look awsome. Now if only San Francisco%26#39;s beaches were only half as good as Hawaii%26#39;s beaches.
