Questions & Answers about Yo cuido mucho a mi familia.
In Spanish, subject pronouns (yo, tú, él…) are usually omitted because the verb ending already shows who the subject is.

Using yo adds a bit of emphasis or contrast, like:
That a is the “personal a”, used before a direct object that is:
- a person,
- a group of people,

Compare:
- Cuido a mis hijos. (people → personal a)
- Cuido mi coche. (thing → normally no a)
You normally do not use the personal a with objects, unless you personify them (e.g. talking about a pet like a family member: Quiero mucho a mi perro).
