-다가 shows that one action was going on, and then another action happened or the situation changed.

So 울다가 다시 웃었어 suggests:

• the child was crying
• and then switched to smiling/laughing again

It often feels more vivid than a simple and in English. It highlights the change in the middle of an ongoing action.

Compare:

• 울고 다시 웃었어 = cried and then smiled again
• 울다가 다시 웃었어 = was crying, then smiled again / switched from crying to smiling again

So here, -다가 helps show that emotional turn.

는 is the topic marker, while 가 is the subject marker.

In this sentence, 그 아이는 means the speaker is setting up that child as the topic and then saying what happened with that child.

Using 는 can feel like:

• as for that child...
• that child, on the other hand...
• or simply a topic already known in the conversation

If you said 그 아이가, it would put more direct focus on the child as the subject of the event. Both can be possible depending on context, but 그 아이는 sounds very natural when talking about someone already being discussed.

Literally, 그 아이 is that child or that kid.

But in actual usage, it often refers to:

• a child already mentioned before
• a child both speakers can identify
• sometimes just the child in natural English translation

So even though 그 literally means that, English might translate it more naturally as:

• the child
• the kid
• sometimes even he or she, depending on context

Korean often keeps using nouns like 그 아이 where English might switch to a pronoun.

This is because 괜찮다 has to change into a form that can modify a noun.

Here, the noun is 것.

So:

• dictionary form: 괜찮다
• noun-modifying form: 괜찮은
• phrase: 괜찮은 것

This is similar to how English uses different structures before nouns. In Korean, descriptive verbs such as 괜찮다 change form when they directly describe a noun.

So:

• 괜찮아 = is okay
• 괜찮은 것 = a thing/situation that is okay

And then 처럼 attaches to that phrase.

것처럼 means like, as if, or as though.

The pattern here is:

• A-(으)ㄴ 것처럼
• V-는 것처럼

It means something seems like that state or action.

So 괜찮은 것처럼 means:

• as if okay
• like he/she was okay
• as though nothing was wrong

In natural English, you would not usually translate 것 literally as thing here. The whole expression works as one grammar pattern meaning as if.

Not necessarily.

That expression focuses on appearance or impression, not a confirmed fact. It suggests that the child smiled again as if they were okay.

So the nuance is:

• maybe the child really did calm down
• but the speaker is not fully stating that as a fact
• the speaker is describing how it looked

This makes the sentence a little more subtle than simply saying:

• 그 아이는 다시 괜찮아져서 웃었어
  = the child became okay again, so smiled

Your original sentence keeps a bit of distance and says the child seemed okay.

다시 means again.

In this sentence, it shows a return to a previous state:

• first the child was crying
• then the child smiled again

So 다시 helps express that the child went back to smiling after crying.

Without 다시, the sentence would still make sense, but it would lose that strong sense of returning to smiling.

웃다 can mean both to smile and to laugh.

Which one sounds best depends on context.

In this sentence, English speakers might often choose smiled again, because the image is a child crying and then looking okay enough to smile. But laughed again is also possible if the situation was more animated.

So:

• 웃다 = smile / laugh
• context decides the best English translation

This is common in Korean: one verb can cover a range that English splits into two separate verbs.

In Korean, the tense of the whole sentence is often shown mainly on the final verb.

So in:

• 울다가 ... 웃었어

the final 웃었어 tells you the whole event is being described in the past.

The earlier connected verb 울다가 does not need its own past marker here. That is very normal Korean sentence structure.

A very literal way to think of it is:

• while crying / after crying, the child smiled again

The past meaning is already clear from the ending.

Yes, by default, that is how this sentence is understood.

In Korean, when one subject is introduced and then multiple connected actions follow, the subject normally stays the same unless something marks a change.

So here, the natural reading is:

• the child was crying
• the child smiled again

You do not need to repeat the subject for each verb.

You could, but the nuance changes.

• 울고 다시 웃었어 = cried and then smiled again
• 울다가 다시 웃었어 = was crying, then smiled again / switched from crying to smiling again

-고 simply links actions. -다가 emphasizes the transition more strongly, often as a shift during an ongoing action or state.

So in your sentence, 울다가 is a very good choice because it captures that emotional flip from crying to smiling.

웃었어 is the casual, informal ending.

It is used:

• with friends
• with younger people
• in narration with a casual tone
• in intimate or relaxed speech

If you want the polite version, you would say:

• 그 아이는 울다가 괜찮은 것처럼 다시 웃었어요.

And a more formal written or official style would be:

• 그 아이는 울다가 괜찮은 것처럼 다시 웃었습니다.

So the grammar is the same; only the speech level changes.
