Very little sleep
Infants often sleep 14 to 18 hours a day, children only wake up when hungry, go to the toilet and be uncomfortable. However, this rule does not apply to children with high IQ. Children will only sleep less than that average.
Get up to observe everything
If mothers see that their child does not cry nor scream after waking up, on the contrary, they are very focused on observing their surroundings, very curious about everything around them. Such a child is very good at thinking, in his heart is also very strong. If the child has such an expression, the IQ is very high, the personality is very calm and independent.
After waking up, play by yourself
Some children after waking up will play with their tiny fingertips. There are kids who play for a while after waking up, when they are bored, they will start screaming to catch the attention of adults. Such a child will be very smart.
Normally this shows that the ability of children to adapt very well, the ability to exercise is also very strong. If the mother discovers that the child has such symptoms after waking up, then the child has a high IQ.
