In general, "brother" is a frequent noun. It is not the name of a particular brother. As a result, it is rarely capitalized. The only time I can think of when "brother" would be capitalized as a proper noun is if you were referring to Jesus Christ as your brother. Otherwise, use his full name.
Similarly, "sister" is a common noun, so it is not capitalized as a proper noun. Sister refers to any female sibling, whether they are older or younger than you. Again, the only time I can think of when "sister" would be capitalized as a proper noun is if you were referring to Jesus Christ as your sister.

Little Brother's name is not capitalized. Neither of the two terms is a proper noun, which must be capitalized. It would have been a different story if it had been his name. Then Little Brother would have been a proper noun.
These terms are only capitalized when they are used as proper nouns. "Brother" is an identifying label, not a proper noun in "The younger brother went to the shop" (assuming the person does not go by the name "The Younger Brother"). In general usage, non-personal pronouns and common words are not capitalized.
When used as honorifics or titles, sister and brother are capitalized similarly to doctor. When used with an article or possessive pronoun, you would not uppercase them (or "mom" or "dad"). "My sister" and "my brother," as well as "my mom" and "my dad," are accurate. "My brother's" is not correct because it refers to more than one person. Similarly, "their sister" and "their brother" are incorrect.
However, when they are part of a phrase that functions as an adjective, they can be uppercased like any other word: "her brother" and "his sister." This may seem counterintuitive at first, but it makes sense when you think about it: both words are modifying the same noun ("sister") so they should be treated equally.
In general usage, sister and brother are not capitalized unless they are used as names of people. Otherwise, they are lowercase.
The distinction between brother and sibling as nouns is that a brother is the son of the same parents as another person, but a sibling is someone who has the same parents as one's brother or sister. A brother and a sister are two members of a family whose parents were also siblings; therefore, they are siblings.
Brothers and sisters usually have the same mother and father, but not always. Some mothers are only children while others have several brothers and sisters. The same thing goes for fathers--some have many sons and daughters, while others are the only ones in their families to be born into life. This fact about families makes it possible for there to be differences between brothers and sisters in terms of age, role models, etc.
As far as jobs are concerned, brothers and sisters often work together because they need one another's help when raising a family. However, this isn't always the case because some sisters have careers while others stay at home with the kids. Brothers can be employed in many different types of jobs but most often they work in occupations where they get to meet people's needs each day--such as teachers, nurses, doctors, etc.
Finally, brothers and sisters share many other experiences together including good times and bad. No matter what, they always need one another so it is important to keep communication open between them.
When family-related phrases are used as proper nouns (as names), they are capitalized. When the words are used as common nouns (rather than names), they are not capitalized.
The proper noun for "family" is familial.
Familial means relating to or belonging to a family: a familial relationship.
Thus, this word can be used to describe the relationship between two people who are parents and children, siblings, cousins, aunts and uncles, or any other family member.
This word should not be confused with familial, which means related by blood. The words are not interchangeable. Your family may very well be friendly, but that doesn't make them familial. Only blood relatives are considered for purposes of protection under the law. A friend's child could be injured in an accident with your brother-in-law; therefore, he would be considered familial and you would be expected to help him.
Families often have strong bonds among their members. If you use this word as a name for such a group, use it without capitalizing its letters.
In American English, the word "familial" is also used to describe something that is familiar.
As previously stated, "brother" can be either a noun or a verb. My parents adore both me and my younger brother equally, despite the fact that he is adopted. Therefore, "brother" can be used as a noun to refer to someone who people love equally, or it can be used as a verb to describe how you feel about someone.
There are seven parts of speech in English. They are nouns, pronouns, verbs, adjectives, adverbs, prepositions, and conjunctions. "Brother" can be used as any of these parts of speech.
Nouns are words that name people or things. "Brother" is a noun because it tells us what type of word it is by naming another person. Nouns always start with a capital letter and have a singular form as well as a plural form. So, the singular form of the word "brother" is the same as its plural form: one brother or many brothers.
Pronouns are words that replace a name or a person mentioned earlier in the sentence. Pronouns can also replace a noun or a pronoun.
When referring to a sister utilizing the connection, the diminutives Sis and Bro are more commonly used. If you write "hello, Sis," uppercase it for the same reason Mom did. When used as regular nouns, they are not capitalized.
Siblings is a proper noun meaning people who are born into the same family or couple. Siblings can also be referred to as co-twins.
Using "sibling" as a proper noun makes sense when talking about your own siblings because it tells us something about you, your family, and their relationship to one another. Siblings from other families would not need to be capitalized.
Diminutive forms of words are often used to address friends, family, and others close to you. Because sisters and brothers come from the same parents, they are called sibling pairs. Other sibling groups include half-siblings and stepbrothers and stepsisters.
Half-siblings have one parent in common while stepbrothers and stepsisters have two parents in common. Sometimes half-siblings will get along well while stepbrothers and stepsisters do not. The difference lies in how they were raised by their parents; half-siblings are usually given equal treatment while stepchildren are usually treated differently.
