Después de comer, mi hija se quedó mirando las moras y los arándanos como si fueran una sorpresa.

In Spanish, after después de, you normally use an infinitive when the subject is the same and the action is expressed generally:

• después de comer = after eating / after lunch
• después de salir = after leaving

Spanish does not use the gerund here the way English often uses -ing.

If you wanted to mention a different subject or make it a full clause, you would use something else, for example:

• Después de que comió... = After she ate...

But in your sentence, después de comer is the natural compact form.

It can mean both, depending on context. In everyday Spanish, comer often refers not just to eating in general, but specifically to having a meal, especially lunch in Spain.

So here, Después de comer could naturally be understood as:

• After eating
• After lunch

Both are good interpretations.

Se quedó mirando adds a special nuance. It means something like:

• she remained looking
• she started and stayed looking
• she just stood there staring

So:

• miró = she looked
• se quedó mirando = she kept looking / she was left staring / she stared

This structure often suggests a pause, a reaction, or that the person became absorbed in what they were seeing.

Quedarse + gerundio is a common structure that means someone ends up staying in a certain action or remains doing something.

Examples:

• Se quedó dormido = He fell asleep / ended up asleep
• Se quedó esperando = He stayed waiting
• Se quedó mirando = She stayed looking / stared

In your sentence, it suggests that the daughter didn’t just glance at the berries—she lingered, looking at them.

After quedarse, Spanish commonly uses the gerund to describe the action that continues:

• se quedó mirando
• se quedó pensando
• se quedó esperando

Using a + infinitive would sound unnatural here.

So:

• se quedó mirando = natural
• se quedó a mirar = generally not what standard Spanish would use in this context

Spanish uses definite articles more often than English. Here, las moras y los arándanos refers to the berries that are present in the situation—the ones she is looking at.

In English, we might simply say:

• blackberries and blueberries

But Spanish often prefers:

• las moras y los arándanos

This does not necessarily mean all blackberries and blueberries in general; it can just mean the blackberries and blueberries there in front of her.

In Spain:

• moras usually means blackberries
• arándanos usually means blueberries when the context is fruit you eat

Technically, arándano can also refer to other berry types such as cranberry in some contexts, so Spanish labels can vary by region and product. But in a sentence like this, a learner will usually understand arándanos as blueberries.

Because como si is normally followed by the imperfect subjunctive in Spanish when expressing an unreal comparison.

So:

• como si fueran = as if they were

This is the standard pattern:

• Me habla como si me conociera. = He talks to me as if he knew me.
• Lo miró como si fuera un fantasma. = She looked at him as if he were a ghost.

Using eran or son after como si would be incorrect here.

Because the verb agrees with the subject, not with the noun after ser.

The subject is:

• las moras y los arándanos → plural

So the verb must be plural:

• como si fueran una sorpresa

Even though una sorpresa is singular, that is the complement, not the subject.

In English, this works similarly:

• as if they were a surprise

They is plural, even though a surprise is singular.

Yes. Fueran and fuesen are both imperfect subjunctive forms of ser.

So these are both correct:

• como si fueran una sorpresa
• como si fuesen una sorpresa

In modern everyday Spanish, -ra forms like fueran are more common, but fuesen is also perfectly correct and natural.

Spanish often uses possessives like mi, tu, su in the same kind of places English does:

• mi hija = my daughter

You could not normally omit mi here unless the context already made it very clear and the sentence was reworded in a different way. So mi hija is the straightforward, natural choice.

The comma separates the introductory time expression from the main clause:

• Después de comer, = introductory phrase
• mi hija se quedó mirando... = main clause

This is very similar to English:

• After eating, my daughter...

In Spanish, the comma is common and helps readability, especially when the opening phrase comes first.

Yes, very often it does—especially in this sentence.

On its own, se quedó mirando suggests that she stopped and looked for a moment, often with some emotional reaction such as:

• surprise
• confusion
• fascination
• disbelief

Then the next part reinforces that idea:

• como si fueran una sorpresa = as if they were a surprise

So the whole sentence gives the feeling that the daughter stared at the berries as though she hadn’t expected them or found them oddly striking.

It could, but the meaning and style would change slightly.

• como si fueran una sorpresa = as if they were a surprise
• como si fueran sorprendentes = as if they were surprising

The original is more idiomatic and expressive. It treats the berries almost like the event of a surprise, not just as surprising things. That makes the sentence feel a bit more vivid and natural.

Yes, it fits Spain Spanish very naturally, though it would also be understood elsewhere. A few things that sound especially normal in Spain include:

• después de comer often meaning after lunch
• arándanos for blueberries
• the overall rhythm and phrasing of se quedó mirando

So while the sentence is broadly standard Spanish, it does sound very comfortable in a Spain context.
