Answer:
In the paragraph, the incorrectly conjugated verb is marked in bold and underlined:
- Hijos, acuéstense. Antes de acostarse, pónganse los pijamas y lean un poco. No se olviden de cepillarse los dientes. No se <u>hable</u> cuando se metan en la cama. Buenas noches.
The correct conjugated form of the verb in that sentence could be:
- No <u>hablen</u> cuando se metan en la cama.
Explanation:
The noun usually used in the paragraph is <u>children</u> and could be replaced by the personal pronoun <u>'you'</u> which translation is <em>'ustedes'</em> in Spanish, the sentence with the incorrectly conjugated verb has the verb <em>'hablar'</em>, which is conjugated in the impersonal form how is below:
1. Yo <em><u>hable</u></em>.
2. Tú <em><u>hables</u></em>.
3. Él <em><u>hable</u></em>.
4. Ella <em><u>hable</u></em>.
5. Ello <em><u>hable</u></em>.
6. Nosotros <em><u>hablemos</u></em>.
7. Ustedes <em><u>hablen</u></em>.
8. Ellos <em><u>hablen</u></em>.
How you can see, the correctly conjugated for the verb <em>'hablar'</em> with the personal noun <em>'ustedes'</em> is <em>'hablen'</em> without the object pronoun <em>'se'</em>.
