There are some developmental concerns if he just uses head nodding and that too not meaningfully.

Please get a detailed Development Screening done in person. ( language , attention , eye contact and other similar tasks are being evaluated) . Also record video of child when such episode occurs for proper review. This type of behaviour can range from being normal ( which improves with age in children) to some behaviour disorder.

Developmentally - 2 year old child shud be able to walk on his own, grab objects with two fingers , able to scribble , ask for things , speak 2 word sentences. Child with reduced attention span and nit able to express with words but by gestures needs evaluation to rule out behavioral disturbances/disorders

Hello there, you should record video and share, so proper description and actions can be seen , if it's normal or not. Mostly your description seems normal. But better to evaluate to prevent any complications later. Do consult online and get prescribed properly with history.

At 2 yrs of age : should talk 2 word sentences Should respond when we call him his name So looks like some delayed mile stones are there Urgently take to Pediatrician physically to evaluate further

Not normal
