Hoje tenho de comprar fraldas e um biberão antes de ir buscar a bebé à creche.

Tenho de comprar means I have to buy or I need to buy.

In European Portuguese, ter de + infinitive is a very common structure for obligation or necessity:

• tenho de comprar = I have to buy
• tens de estudar = you have to study
• temos de sair = we have to leave

The de is just part of this pattern. You normally cannot drop it in standard Portuguese.

A close alternative is preciso de comprar (I need to buy), but tenho de is extremely common and natural.

Hoje means today.

Putting it at the beginning is very natural because it sets the time frame right away:

• Hoje tenho de comprar... = Today I have to buy...
• Tenho de comprar... hoje = I have to buy... today

Both are possible, but starting with Hoje often sounds more natural when the speaker wants to emphasize today as the important time reference.

Fraldas means nappies/diapers, and it is very often used in the plural because people usually buy more than one.

So:

• comprar fraldas = buy diapers/nappies
• comprar uma fralda = buy one diaper/nappy

Using the plural here sounds very normal, because the idea is usually a pack of diapers or simply diapers in general.

Because the sentence treats the two nouns slightly differently:

• fraldas = diapers/nappies in a general, unspecified sense
• um biberão = one baby bottle

So the meaning is roughly:

• buy diapers and a baby bottle

If you wanted, you could also say umas fraldas, but bare plurals like fraldas are very common in Portuguese when talking about unspecified things in general.

Yes. Biberão is the usual European Portuguese word for baby bottle / feeding bottle.

This is a good regional vocabulary point:

• European Portuguese: biberão
• Brazilian Portuguese: often mamadeira

So if you are learning Portuguese from Portugal, biberão is the normal word to learn.

Antes de means before when it is followed by a verb in the infinitive or by a noun phrase.

Examples:

• antes de sair = before leaving
• antes de comer = before eating
• antes da aula = before the class

In your sentence:

• antes de ir buscar a bebé à creche = before going to pick up the baby from nursery/daycare

Because ir buscar is a very common Portuguese expression meaning to go and get or to go pick up.

So:

• buscar by itself can mean to fetch / get
• ir buscar adds the idea of going somewhere in order to get someone/something

In this sentence, the speaker is not just fetching the baby in an abstract sense; they are going to the nursery/daycare to pick her up. That is why ir buscar fits very naturally.

As a whole, ir buscar means:

• to go get
• to go fetch
• to go pick up

It is best learned as a very common fixed expression.

Examples:

• Vou buscar o carro. = I’m going to get the car.
• Fui buscar as crianças à escola. = I went to pick up the children from school.
• Tenho de ir buscar pão. = I have to go get bread.

So in your sentence:

• ir buscar a bebé = to go pick up the baby

Because when the subject is the same as in the main clause, Portuguese usually just uses antes de + infinitive without repeating the subject.

Here, the subject of both actions is the same person:

• tenho de comprar...
• (eu) ir buscar a bebé...

So antes de ir buscar is the natural, concise form.

You could say antes de eu ir buscar, but it is less necessary here and usually sounds more explicit than needed.

Because bebé can be either masculine or feminine depending on the child’s sex:

• o bebé = the baby boy / the baby (masculine)
• a bebé = the baby girl

In this sentence, a bebé tells you the baby is female.

English uses just the baby, so this is something English speakers often notice in Portuguese.

Sometimes Portuguese can omit articles in certain contexts, but here a bebé sounds the most natural.

Portuguese often uses definite articles more than English does. So where English says:

• pick up the baby

Portuguese naturally says:

• ir buscar a bebé

Using the article here is normal and idiomatic.

Because à is a contraction of:

• a = to
• a = the

So:

• a + a creche = à creche

This happens because creche is feminine:

• a creche = the nursery/daycare

And the verb phrase implies movement towards that place:

• ir ... à creche = go to the nursery/daycare

The grave accent marks this contraction.

Because à creche means to the nursery/daycare, while na creche means in/at the nursery/daycare.

Compare:

• Vou à creche. = I’m going to the nursery/daycare.
• Estou na creche. = I’m at/in the nursery/daycare.

In your sentence, the idea is the destination of going to pick up the baby, so à creche is the right choice.

Creche usually means a place where very young children are looked after during the day.

Depending on context, English translations might be:

• nursery
• daycare
• day nursery

In Portugal, creche is especially associated with very young children, younger than typical school age.

Yes, very much so. It has several very common European Portuguese features:

• Hoje at the beginning for time framing
• ter de + infinitive for obligation
• antes de + infinitive
• ir buscar for go pick up
• à as a contraction with a feminine destination noun
• vocabulary like biberão and creche, both very typical in Portugal

So this is a very natural everyday sentence in European Portuguese.

In European Portuguese:

• bebé sounds roughly like buh-BEH
• biberão sounds roughly like bee-buh-ROWNG, with the final -ão being a nasal sound

A few helpful pronunciation points:

• The stress in bebé is on the last syllable.
• The stress in biberão is also on the last syllable.
• The ending -ão is very characteristic in Portuguese and does not sound exactly like any normal English ending.

If you are learning European Portuguese pronunciation, these stress patterns are important to notice.
