Quando a bebê começa a chorar, eu a pego no colo.

Because bebê can refer to either a male or a female baby, and the article shows the gender here.

• a bebê = the baby girl / the female baby
• o bebê = the baby boy / the male baby

So in this sentence, a bebê tells you the baby is female.

A lot of learners expect the noun ending to decide the gender, but with bebê, the article is what makes it clear.

That a is not an article. It is a direct object pronoun meaning her.

So:

• a bebê = the baby girl
• eu a pego = I pick her up

This pronoun replaces a bebê so you do not repeat the noun.

A literal breakdown would be:

• eu = I
• a = her
• pego = pick up / take

So eu a pego means I pick her up.

Both exist, but they are used differently.

• eu a pego is more formal, more common in careful writing, and more traditional grammar
• eu pego ela is very common in everyday spoken Brazilian Portuguese

So this sentence is grammatically correct and natural, but it sounds a bit more polished or written.

In casual speech, many Brazilians would say:

• Quando a bebê começa a chorar, eu pego ela no colo.

Even though traditional grammar prefers eu a pego, learners should recognize both.

This is the structure:

• começar = to begin / to start
• a = to
• chorar = to cry

So começar a + infinitive means to start doing something.

Examples:

• começar a falar = to start speaking
• começar a correr = to start running
• começar a chorar = to start crying

This is a very common Portuguese pattern.

Yes, but the meaning changes slightly.

• Quando a bebê chora = when the baby cries
• Quando a bebê começa a chorar = when the baby starts crying

The version with começa a chorar focuses on the beginning of the crying. It suggests the speaker reacts right when it starts.

Because Portuguese, like English, often uses the present tense for habitual actions or things that usually happen.

So this sentence means something like:

• Whenever the baby starts crying, I pick her up.

It is not necessarily talking about one specific moment. It can describe a regular pattern.

That is why:

• começa = starts
• pego = I pick up

are both in the present tense.

No colo is a very common expression in Brazilian Portuguese. Here it means something like:

• in my arms
• up in my arms
• sometimes on my lap, depending on context

In this sentence, pegar no colo means to pick up and hold someone, especially a baby or small child.

So:

• eu a pego no colo = I pick her up in my arms

The expression is idiomatic, so it is best to learn pegar no colo as a chunk.

Because no is a contraction of:

• em + o = no

And colo is a masculine noun, so it takes o:

• o colo

That gives:

• em o colo → no colo

This kind of contraction is very common in Portuguese:

• em + a = na
• em + os = nos
• em + as = nas

Not always. Portuguese often drops subject pronouns when the verb already makes the subject clear.

So you could say:

• Quando a bebê começa a chorar, pego-a no colo.
• Quando a bebê começa a chorar, eu a pego no colo.

Both are correct.

Why include eu here?

• for emphasis
• for clarity
• because Brazilian Portuguese uses subject pronouns more often than European Portuguese

So eu is optional, but very natural.

Because the sentence begins with a dependent clause:

• Quando a bebê começa a chorar = when the baby starts crying

Then comes the main clause:

• eu a pego no colo = I pick her up

Putting a comma after the introductory quando clause is standard and helps readability.

In some kinds of Portuguese, yes, but in Brazilian Portuguese everyday usage, before the verb is much more common.

You may see:

• eu a pego = I pick her up

In more formal written Portuguese, especially with infinitives or certain structures, you might also see other placements, such as pegá-la. For example:

• Vou pegá-la no colo. = I’m going to pick her up in my arms.

But in this sentence, eu a pego is the expected form.

It is correct and understandable, but it sounds a bit more careful or written because of eu a pego.

In natural everyday Brazilian speech, many people would more likely say:

• Quando a bebê começa a chorar, eu pego ela no colo.

Or even:

• Quando a bebê começa a chorar, pego ela no colo.

So the original sentence is good for learning grammar, especially object pronouns, but the spoken version is often a little different.
