しばらく様子をみましょう。

Let’s wait for a while and see how you do.

Is this Japanese sentence natural-sounding?

@ericaw
Yes, very natural. You can use the phrase しばらく様子をみましょう in the following situations:

  1. A doctor says to his patient “I’ll prescribe this mild medicine first. Let’s see for a while how your symptoms will be improved. If it gets worse, come back to my office later.” ==> この薬を飲んで、しばらく様子をみましょう。

  2. Financial sanctions by US on Russia are all done. Let’s see how Russian people may react. ==> アメリカがロシアにできる経済制裁の手は全て打った。あとはしばらく様子をみよう。
