How do you say baby bear in native American?

There are more than 300 North American Native languages. Many are as different as Chinese, English and Arabic.

In Dine' bizaad, (Navajo Language) little bear is shash yázhí

yázhí means little or young and the marks over the vowels mean they are high tone. The zh is pronounced like the middle of the Word measure.

Baby is: awééʼ

So it could be shash awééʼ as well.

This is high tone too with a glottal stop at the end.
