To tell if your baby is intelligent you can look for some signs of intelligence in your baby.
Some signs that your baby is intelligent include.
Born with his/her "eyes wide open"
Preferred to be awake rather than asleep.
Noticed his/her surroundings all the time.
Grasped the "bigger picture" of things.
Counted objects without using his/her fingers to point to them.
Constant stimulation-seeking while awake.
Earlier ability to mimic sounds than other babies.
Extreme alertness or always looking around.
The age at which a kid can count to 10 is 4 years old.
The age of 4 is the average age when a kid can count to 10 although some kids may take a bit longer and some kids may learn to count to 10 before 4 years of age.
The average child can count up to “ten” at 4 years of age, however it is normal for children to still be learning to count to 5 while others are able to correctly count to forty.
Some 2 year olds can count to 10 as well.
Most 2 year old children are capable of counting to 10 although they may mix up the order of the numbers.
Begin practicing numbers and counting with your toddler to help build a strong foundation for number fluency.
Daily number practice with colorful flash cards and counting games can make learning fun for your child.
But, at what age do children start to understand numbers?
The truth is, children will recite numbers before they actually understand the concept behind them.
Though every child is different, most toddlers will be able to count to 10 by the time they are two-years-old.
By age 2, a child can count to two ("one, two"), and by 3, he can count to three, but if he can make it all the way up to 10, he's probably reciting from rote memory.
Kids this age don't yet actually understand, and can't identify, the quantities they're naming.
