There are some clear signs that your child may be a genius and that you should nurture their genius accordingly.
Children start showing signs of a genius mind quite early. Their actions, their attitudes, and their thoughts play a great role in determining their exceptional abilities. A careful observation would, therefore, help you identify them early and give them the best possible start.

#1 They are curious

A great mind is, first and foremost, a curious mind. A child starts showing curiosity quite early and they can be full of questions. Their questions may be anything but what one needs to pay attention to is that they feel excited about their questions and keep asking.

Sometimes, your child’s question may stump you. The fact is that a genius child starts making sense of the world early and they try their best to inculcate everything into their intellectual frames. The best way forward is to satisfy their curiosity and encourage them to ask more.
#2 They take charge

A genius child would also show early signs of leadership. They may show clear signs that they need to take charge and change a particular situation according to their own needs. They also show signs of being in command, if you observe closely.

Your child may dictate the games they play with other kids. They may be the ones to decide what their friends should do. Things as simple as these indicate leadership signs which should be encouraged in order to boost their self-belief.
#3 They may have great mood swings

It is a fact that people who are geniuses do not feel content quite easily. They need to do one thing or the other and keep their minds occupied. They need to be engaged in something they deem productive and they hate wasting time.

These signs are also visible in childhood. Your child may feel bored quickly but show signs of creativity at the same time. They may feel annoyed when they have nothing to do and feel extremely involved in something which challenges them mentally. This is a great sign of good mind.
#4 They are quick learners

A mind which is above average would process information quite easily and would move on to gain more knowledge. They would learn quickly and then hone their skills. They would then fond something else to learn and apply their mind to the new task.

If you observe that your child is a quick learner and that they move from one thing to the next quite quickly (after learning them, of course) then it is a good sign that your child is mentally very active. A quick learning child would also learn more and apply those learnings better.
#5 They have a good vocabulary

Genius people have been observed to have great vocabularies. This is because they need better and more accurate words to describe their ideas. They need to articulate better and that is why they need a varied list of words to frame their sentences.

Your child may show signs of genius with their curiously incredible vocabulary. They would learn words quite easily and also learn to apply them in sentences. A good vocabulary is indeed a great sign and the child should be encouraged to learn more.
#6 They may be musically gifted

It has been observed that a lot of the genius minds of humanity had a great ear for music. They were either good composers, musicians, or showed inclinations towards finer music all their lives. The ability to identify and listen to good music is a sign of a gifted mind.

If you observe that your child has a good inclination towards music, either playing or listening, then you may encourage their behavior. Good music plays a great role in shaping beautiful thoughts and your child just may find the music uplift their talents.
#7 They like spending time alone

Gifted children would have the urge to have more time for themselves so that they can freely do whatever it is that they are interested in. They may like reading, playing music, listening to music etc. but they would need the time to do it without being disturbed.

This does not mean that you leave them unsupervised but that you may need to give them their leisure time. You should let them feel confident in their abilities and give them the space they need to grow their talents as they wish to.
#8 They experiment

A curious mind is not satisfied with learning itself. It has to use that learning to know more. To do this, your child would experiment. They would do small things which may not seem much to you but it is their way of putting their knowledge to test and identifying this trait would help you give them the best possible start.
