Doesnt understand questions?

[Tjorven64]

Me:
How old am I?

5 year old DS: I'm 9 years old.

Me: how old is mummy?

Ds: I'm 5 years old....no...I'm zero years old.

ME: How old is grandma?

DS: shes a pet dog.

Is this normal conversation I'm having with a kid who's 5? The average 5 year old should know how to answer these easy 3rd degrees am i right?

Is it your child?

Is he tied to a chair, with a strong light shining in his eyes?

Seriously, if he feels under pressure to perform, he may be using distraction to get you off his back. My dc would feel very uncomfortable being quizzed, especially on things like grandma 's age, they wouldn't have a clue at age 5. I think he's being very creative.

She's a pet dog. Howling! 😂

Chill, he probably doesn't take an interest in your age.

If you ask him questions about subjects he actually has an interest in, how does he respond?

We regularly have sessions in our Yr1 class, where he children have to ask each other questions. Some of them find it incredibly difficult and often just make a statement. I wouldn't worry about it but keep practicing.

I agree with HairyDogs - if you’re seriously worried perhaps switch it up and talk, asking questions, on a walk or in a context where it’s fun and exciting.

I don’t know, like “What animals do you think might live in this wood? Who did the mouse meet in the Gruffalo?”

He's able to answer questions he's interested in like do you like your james train and things like that.
He doesnt understand why? questions and will linger if I ask him why did you throw your toy or break your toy?
He will just linger and doesnt seem to understand how to respond.

Yes he's my child.

I think it's normal that kids don't know their parents age,

Often children give the answers they wish were true... and regularly ignore things they aren't interested in.

'Why' questions are really hard for children (and indeed some adults). They need a well developed sense of internal awareness and ability to name feelings. Sometimes when I'm angry or frustrated i might do something that if you asked me why, I'd be stumped for an answer.
You can help him by putting the name of the feeling to his actions, e.g. 'you threw that toy because you are angry at me for not giving you the chocolate'. Or even, 'i see you are angry, let's do this instead'.

A five year old won’t be able to explain/articulate the “why” of everything. His answers sound like he’s trying to be funny- and he is bright.

If you’re really worried, ask a pediatric specialist.

Does he converse normally in other ways?

Sounds like he's just not interested in what your asking. Not many 5 year olds know how old their parents are, as to them you're ancient
And as for the avoidance of answering when he's misbehaved, that's normal.

I'm 30 and I don't know my parents or grandparents ages.

Why questions are very hard to articulate, especially the ones in your example. Sounds like a typical 5 year old from what you describe.
