Rashi
I calmed and quieted my soul upon You, like a suckling who is placed upon his mother. גָמוּל is one who sucks the breasts.
Rashi
like a suckling was my soul with me My soul within me was before You as an infant sucking its mother’s breasts.
Mei HaShiloach
"A song of ascents. Of David. Ha-Shem, my heart is not proud, nor my look haughty; I do not set my path to greatness or wonderous things beyond me; except that I have set before me and contented my soul, the same way a child does who is weaned from their mother; I am like a weaned child in my soul." (Psalm 131:1-2). It's as if David ha-Melech (peace be upon him) is saying before ha-Shem (may ha-Shem be blessed), that even with all the sins that Israel has committed, we aren't separated from ha-Shem. It's merely like a toddler, who has separated from their mother's breasts, yet even with they turn their face away from their mother, to pick up something or other, they turn their gaze back to their mother, to make sure she's not going anywhere! Thus it is, on every occasion when Yisrael desires something well, that they direct their gaze to ha-Shem and make sure that ha-Shem has not turned away from them. We can bring this from the Gemara (Beitza 11a, discussing the case of whether a fledgling dove is permitted if its nest cannot be definitively identified, concluding that) the mishna therefore teaches us that anywhere that a fledgling hops and turns and sees its nest [or its mother], it will continue to hop. But if it can no longer see its original nest, it will not hop any farther. And the community of Yisrael is comparable to a dove, as is understood (Shabbat 49a).
