Ya know, maybe he is just not ready for full on real food yet.
His foods, should still be soft, minced, etc.
He is choking... so he is still getting used to things/eating.
No worries.
Don't compare him to other kids.
Each kid is different.
Kids do not ALL do things at the same time or same age.
It just is.
Your Pediatrician is not concerned.
It is fine.
At this age, a child is NOT fully independent about eating/feeding themselves nor able to chew anything and everything.
They choke.
They also often, put too much in their mouths. They do not know about portion sizing. So they always have to be supervised.
He is 1 years old.
He is not his cousin.
Is your son able to pick up other things with his hands, like toys?
Or can he grab things like his toys?
If so, then he has a pincer grasp and can pick things up.
With food, he is still not comfortable yet.
MANY kids this age do and will need help with eating.
Heck, my son when 2 years old, still needed help eating.
Its fine.
They at these ages, do not eat like older kids, at all.
Don't worry.
Or he will get food hang-ups and eating hang-ups. Which can create eating disorders.
Just go by HIS cues.
Kids this age, also have developing taste buds, and do not eat anything and everything.
Just like adults.
He likes to eat from you or Grandma. Fine.
No biggie.
He is just more comfortable with you/bonded.
My kids, LOVED eating from their Grandma or my plate too.
I remember being that way too, as a child.
No biggie.
For some reason, my kids just said it tasted better from me or Grandma.
Feed your son, what he WILL eat.
Food fluctuations and preferences, are normal and DO happen. All throughout childhood.
Just feed him what he will eat and is not a choking hazard.
Don't think he has to eat just like his cousin.
If he is not eating that much throughout the day, is he at least getting whole milk, Or other things???
How is his growth and weight? On par?
My son, has been picky with eating since 6 months old and texture sensitive. We have NEVER... made eating a forced thing or an issue. He has despite that, always been healthy and in the 95th-97th percentiles. He now at his age of 4... has naturally expanded his palate and will eat more variety now. Naturally.
And, he took time to feed himself too. NO biggie.
all the best,
Susan
