Can you help me with a child development question

[ineverseeu]

(I called EC to ask about this question, but I was told that for a specific question like this, I have to make an appointment with the tutor. Well...since my test is tomorrow, I have no choice but to ask ec practice question online. But I will try to remove this in a week)

Q: what's normal activity for 2 & 1/2 yrs old child?

1- building 9 - 10 cubes

2- jumping using both feet

3- going up the stairs using alternate feet

4- dancing

I chose 3 but the correct answer was 2.

Does anyone know why? I looked up nursing textbooks, websites, and etc. And they all state that jumping using both feet is for 1 1/2 yrs old, and that going up the stairs using alternate feet is for 2 & 1/2 feet.

i found the information in the wong's essentials of pediatric nursing which they used before.

18 mo

walks up stairs with one hand held

jumps in place with both feet

builds tower of 3 or 4 cubes

30 mo

jumps with both feet

stands on one foot momentarily

builds tower of 8 cubes

age 3

goes up stairs using alternate feet; may still come down using both feet on step

builds tower of 9 or 10 cubes

may try to dance, but balance may not be adequate

hope this helps.

so, even that book states that jumping using both feet happens at 1 1/2 years. ...

yeah.... i donno why they say that this happens at 2 1/2 years.

is discrepancy something that I should expect in EC practice test?

The question is what a 2-1/2 year old can do. No discrepancies. The answer is right.

I just guessed the answer was 2 just from my own experience. When my child was 2, he wasn't building any towers with 9 or 10 blocks. I believe their attention span is not quite there yet. 2 yr olds are always jumping around all over the place. At least mine did!
