Rashi on Exodus 2:6/רש"י על שמות ב׳:ו׳

1ותפתח ותראהו lit., AND SHE OPENED IT AND SHE SAW HIM — whom did she see? את הילד THE CHILD. This is the literal sense of the suffix in ותראהו. A Midrashic explanation is (taking את in the sense of “with”— she saw Him with the child): she saw the Shechina with him (cf. Sotah 12b).

2והנה נער בכה lit., AND BEHOLD A BOY WEEPING — Although he was a ילד, “a child”, his voice was like that of a נער, a grown up boy (cf. Sotah 12b).
