Key Points
甘く見る = “to underestimate / take lightly”
The literal image is to see someone as easy or harmless, so the idiom means to judge them too lightly.
Here Mom is warning Meimi not to assume she is clueless or easy to fool.
ママを = the person being underestimated
The particle を marks who is being judged lightly: ママを 甘く見ない.
〜ないことね = firm advice with a warning tone
〜ないこと turns the negative phrase into a rule-like statement: “make sure not to…”
Adding ね softens it into a knowing reminder, so it sounds like “Don’t go underestimating Mom, okay?” rather than a harsh order.
Family-register nuance: ママ
The mother refers to herself as ママ, which is natural in a parent-child conversation.
