Вечером мама кладёт дочку в кроватку и ставит рядом тёплую бутылочку.

Russian often uses the instrumental case for parts of the day when talking about when something happens:

• утром = in the morning
• днём = in the daytime
• вечером = in the evening
• ночью = at night

So Вечером here simply means in the evening. This is a very common time expression and does not need a preposition.

In Russian, the present tense is often used for habitual or regular actions, just like in English:

• Мама кладёт... и ставит... = Mom puts ... and places ...

This can mean something like this is what she does in the evening. It is not necessarily happening only right now at this exact second.

Also, both verbs are imperfective, which fits repeated or usual actions well.

Russian is more specific than English about how something is placed.

• класть / положить = to put something lying down
• ставить / поставить = to put something standing/upright

So here:

• кладёт дочку в кроватку: she lays the daughter in the crib/bed
• ставит рядом тёплую бутылочку: she sets the bottle nearby, probably upright

English often uses put for both, but Russian usually chooses a verb based on position.

Because дочку is the accusative singular form of дочка.

The verb класть takes a direct object, and дочка is that object:

• дочка = nominative
• дочку = accusative

For many feminine nouns ending in -а / -я, the accusative singular changes to -у / -ю:

• мама → маму
• девочка → девочку
• дочка → дочку

Because Russian uses:

• в + accusative for motion into
• в + prepositional for location in

Here the daughter is being moved into the crib:

• кладёт в кроватку = puts into the crib

Compare:

• дочка лежит в кроватке = the daughter is lying in the crib

So:

• в кроватку = direction / destination
• в кроватке = location

These are diminutive or affectionate forms, which are very common in Russian, especially in family contexts and when talking about children.

• дочь → дочка
• кровать → кроватка
• бутылка → бутылочка

These forms can suggest:

• small size
• affection
• tenderness
• a child-related context

So the sentence sounds warm and natural, not cold or formal.

Because the adjective must agree with the noun in gender, number, and case.

Here:

• бутылочка is feminine singular
• it is the direct object of ставит
• so it is in the accusative singular

Therefore:

• тёплая бутылочка = nominative
• тёплую бутылочку = accusative

Both words change:

• тёплая → тёплую
• бутылочка → бутылочку

Рядом means nearby or next to.

In this sentence it is used on its own:

• ставит рядом = places it nearby

That is perfectly normal.

If you want to say next to something specific, Russian usually uses:

• рядом с + instrumental

For example:

• рядом с кроваткой = next to the crib

So in this sentence, рядом just means nearby, with the exact reference understood from context.

И simply means and. It connects the two actions:

• кладёт дочку в кроватку
• и ставит рядом тёплую бутылочку

So the sentence describes two linked actions done by the mother in sequence.

No, Russian word order is fairly flexible, but the order here is very natural and neutral.

• Вечером sets the time first
• мама gives the subject
• then the two actions follow

So this sounds like a normal, smooth description.

You could rearrange parts of the sentence for emphasis, for example:

• Мама вечером кладёт дочку в кроватку...
• Тёплую бутылочку мама ставит рядом...

But the original order is probably the most neutral and natural.

The letter ё is pronounced like yo and is always stressed.

So:

• кладёт sounds roughly like kla-DYOT
• тёплую begins with tyo-

In many printed texts, ё is often written as е, so you may see:

• кладет
• теплую

But the correct pronunciation is still with ё in words where ё belongs. For learners, it is very helpful when texts actually write ё explicitly.
