Μόλις βρήκαμε το μπιμπερό, το μωρό ηρέμησε και δεν ζήτησε πια την πιπίλα του.

Here μόλις means as soon as or once.

So Μόλις βρήκαμε το μπιμπερό, ... means As soon as we found the bottle, ...

This is a very common Greek pattern:

μόλις + aorist verb = as soon as ...

Be careful: μόλις can also mean just in other contexts, as in I just arrived. In this sentence, because it introduces a whole time clause before the comma, it means as soon as.

Βρήκαμε is the aorist form of βρίσκω (to find).

It means we found.

More specifically:

• βρ- = the aorist stem
• -ήκαμε = we ending in the aorist

So:

• βρίσκουμε = we find / we are finding
• βρήκαμε = we found

The aorist is used because the action is seen as a single completed event.

Greek often leaves out subject pronouns because the verb ending already shows the person and number.

So βρήκαμε already means we found.
You do not need to say εμείς βρήκαμε unless you want emphasis, contrast, or extra clarity.

This is very normal in Greek:

• βρήκαμε = we found
• ηρέμησε = he/she/it calmed down
• ζήτησε = he/she/it asked for

Because the subject changes.

In the first clause, the subject is hidden inside βρήκαμε = we found.
In the next clause, the subject is no longer we. It is the baby:

το μωρό ηρέμησε

So Greek states το μωρό to make the change of subject clear and natural.

Without it, the sentence could become confusing, because the listener might briefly expect the same subject to continue.

Ηρέμησε is the aorist of ηρεμώ / ηρεμίζω in the sense to calm down.

It means the baby calmed down.

The aorist is used because the sentence describes the baby’s calming down as a completed change or event:

• first we found the bottle
• then the baby calmed down
• then it stopped asking for the pacifier

If Greek used an imperfect form, it would sound more like an ongoing background action, not a simple completed event in the sequence.

Because Greek ζητάω / ζητώ often takes a direct object for the thing wanted or requested.

So:

• ζήτησε την πιπίλα = it asked for the pacifier

English uses ask for, but Greek usually just uses ζητάω + object.

Compare:

• Ζητάω νερό. = I’m asking for water.
• Ζήτησε βοήθεια. = He/She asked for help.
• Ζήτησε την πιπίλα του. = It asked for its pacifier.

So this is a normal Greek verb pattern, not a missing preposition.

Here πια means anymore or no longer.

So:

• δεν ζήτησε πια την πιπίλα του = it didn’t ask for its pacifier anymore / it no longer asked for its pacifier

In negative sentences, πια is very often used this way.

Examples:

• Δεν μένω πια εκεί. = I don’t live there anymore.
• Δεν κλαίει πια. = He/She isn’t crying anymore.

In Greek, δεν normally comes directly before the finite verb:

• δεν ζήτησε = did not ask

Then πια usually comes after the verb or after the negative-verb group, depending on what sounds most natural in the sentence:

• δεν ζήτησε πια την πιπίλα του
• sometimes also δεν ζήτησε την πιπίλα του πια

Both are possible, but the version in your sentence is very natural and common.

So the important point is:

• δεν goes before the verb
• πια means anymore / no longer and has some flexibility in placement

It contains:

• την πιπίλα = the pacifier in the accusative
• του = his/its in the form of a weak possessive pronoun

So literally:

• την πιπίλα του = his pacifier / its pacifier

In smoother English here, it is usually its pacifier because the possessor is the baby.

Greek very often uses this structure:

• το βιβλίο μου = my book
• το σπίτι της = her house
• την πιπίλα του = his/its pacifier

It is του because the possessor is το μωρό, which is a neuter noun.

In Greek, the weak possessive forms are based on the genitive:

• του = of him / of it
• της = of her
• του is also used with neuter possessors

Since μωρό is grammatically neuter, Greek uses του.

So:

• το μωρό ... την πιπίλα του = the baby ... its pacifier

This is about grammatical gender, not necessarily biological sex.

Because the nouns have different grammatical genders.

• το μπιμπερό = neuter
• το μωρό = neuter
• η πιπίλα = feminine

In the sentence:

• το μπιμπερό is the object of βρήκαμε
• το μωρό is the subject of ηρέμησε
• την πιπίλα is the object of ζήτησε

For neuter singular nouns, nominative and accusative often look the same:

• το μπιμπερό
• το μωρό

But for feminine singular nouns, the accusative article changes:

• nominative: η πιπίλα
• accusative: την πιπίλα

So την πιπίλα shows that it is the direct object.

Μπιμπερό is a borrowed word, but it behaves like a normal neuter noun in Greek.

In everyday use, it is often treated as largely indeclinable in the singular, so you see:

• το μπιμπερό
• του μπιμπερό
• το μπιμπερό

For a learner, the most useful thing is simply to remember:

• it is neuter
• the article is usually το in the singular

So in this sentence, το μπιμπερό is perfectly straightforward: the bottle / baby bottle.

Yes. Greek word order is more flexible than English word order.

This sentence could be rearranged in other ways and still be grammatical, depending on emphasis. For example, Greek often moves things around to highlight what is important.

But the version you have is very natural because it presents the events in a clear sequence:

1. Μόλις βρήκαμε το μπιμπερό
2. το μωρό ηρέμησε
3. και δεν ζήτησε πια την πιπίλα του

So even though Greek allows flexibility, this order is a very normal storytelling order.
