Learn Spanish (Latin America): Normalmente me lavo la cara temprano.

Exactly! Adding -mente to an adjective is the standard way to turn it into an adverb in Spanish, just like adding "-ly" in English. So, normal (normal) becomes normalmente (normally).

Can I put normalmente in a different part of the sentence?

Yes, adverbs of frequency are quite flexible in Spanish! While placing normalmente at the beginning adds a little emphasis, you could also put it right after the verb: Me lavo normalmente la cara temprano. However, putting it at the start or right before the verb is usually the most natural choice.

Why is it la cara (the face) instead of mi cara (my face)?

In Spanish, when you talk about body parts or clothing, you almost always use the definite article (el, la, los, las) instead of a possessive word like mi (my). The reflexive pronoun me already makes it perfectly clear whose face is being washed!

Why do we need me before lavo?

The verb here is lavarse (to wash oneself). Because you are performing the action on yourself, you need the reflexive pronoun me (myself) to match the "I" form of the verb (lavo). If you just said Normalmente lavo la cara, it would sound incomplete, like you are washing some random face rather than your own.
