Meu bebê dorme no berço depois da mamadeira.

Because bebê can be treated as either masculine or feminine in Brazilian Portuguese, depending on the baby’s sex or on how the speaker chooses to refer to the child.

• meu bebê = my baby with masculine agreement
• minha bebê = my baby with feminine agreement

So this sentence could refer to:

• a baby boy, or
• a baby in a more general way, with masculine agreement

If the speaker clearly wants to refer to a girl, minha bebê is also possible.

In Brazilian Portuguese, possessives like meu, minha, seu, nosso can appear with or without an article.

So both of these are possible:

• Meu bebê dorme...
• O meu bebê dorme...

In Brazil, leaving out the article is very common, especially in simple everyday sentences. Both sound natural, though the version without the article often feels a little more direct.

Because dorme is the conjugated form of the verb dormir.

• dormir = to sleep
• dorme = sleeps / is sleeping

Here, the subject is meu bebê, which is third person singular, so the correct present-tense form is dorme.

A quick comparison:

• eu durmo = I sleep
• você dorme = you sleep
• meu bebê dorme = my baby sleeps

It can mean either one, depending on context.

In Portuguese, the simple present often covers both:

• a habitual action: My baby sleeps in the crib after the bottle
• a current action, in some contexts: My baby is sleeping in the crib after the bottle

If you want to make the ongoing action extra clear, Brazilian Portuguese often uses:

• está dormindo = is sleeping

So:

• Meu bebê dorme no berço... can sound habitual or general
• Meu bebê está dormindo no berço... clearly focuses on right now

Because no is a contraction of:

• em
  • o = no

So:

• em o berço → no berço

This is very common in Portuguese and is required in standard usage.

Some useful patterns:

• no = in/on/at the masculine singular noun
• na = in/on/at the feminine singular noun
• nos = in/on/at the masculine plural noun
• nas = in/on/at the feminine plural noun

Since berço is masculine (o berço), you get no berço.

Because Portuguese em is a broad preposition that often corresponds to English in, on, or at, depending on context.

So no berço literally comes from em + o berço, and the natural English translation is in the crib.

You should not expect a one-to-one match between Portuguese and English prepositions. Portuguese chooses the preposition that sounds natural in Portuguese, even if English uses a different one in other situations.

Berço means crib or baby crib.

In some contexts it can also mean cradle, but in modern everyday Brazilian Portuguese, berço is the normal word for a baby’s crib.

So dorme no berço is a very natural way to say sleeps in the crib.

Because da is the contraction of:

• de
  • a = da

The expression is built like this:

• depois de = after
• a mamadeira = the bottle

So:

• depois de a mamadeira → depois da mamadeira

This contraction is standard and very common in Portuguese.

Mamadeira usually means baby bottle in Brazilian Portuguese.

But in a sentence like this, it often refers not just to the object, but to the feeding routine itself. So depois da mamadeira can naturally mean:

• after the bottle
• after having the bottle
• after bottle-feeding

This kind of shorthand is very common in everyday speech.

Because Portuguese uses definite articles much more often than English does.

So where English might say:

• after bottle-feeding
• after the bottle

Portuguese commonly says:

• depois da mamadeira

Leaving out the article here would usually sound less natural in this everyday sentence.

Yes. Portuguese word order is flexible enough that you can move the time phrase to the front.

For example:

• Meu bebê dorme no berço depois da mamadeira.
• Depois da mamadeira, meu bebê dorme no berço.

Both are natural. The second version gives a little more emphasis to after the bottle.

A rough English-friendly pronunciation is:

meh-ooh beh-BEH DOR-mee noo BEHR-soh deh-POYJ dah mah-mah-DAY-rah

A few helpful notes:

• meu sounds roughly like meh-ooh, said quickly
• bebê has stress on the last syllable: beh-BEH
• dorme has stress on dor
• berço has a ç, which sounds like s
• depois in many parts of Brazil sounds close to deh-POYS or deh-POYJ
• mamadeira has stress on dei: mah-mah-DAY-rah

This is only an approximation, but it can help you get started.
