Am I feeding her too much?

One of my mother's group's friend came to visit the other day and she was so surprised (or shall I say, shocked) to see the amount of food Isabel is consuming daily. She said it's waaayyyyy too much as her daughter of the same age is just having 1/4 or at most 1/3 of the portion that Isabel is eating.

I didn't know if I'm really feeding her too much, but so far she would just happily gulp down the food I feed her at meal times, sometimes wanting more.

Here are some examples of what I'm giving Isabel daily:

Early morning around 7am - 210ml of formula milk

Breakfast around 9am:
- half a banana, 1 egg yolk, 6 teaspoon of wheat + water, mixed and mashed into puree



or

- half of a big Fuji apple (steamed and mashed) + 1 egg yolk


Lunch around 12:30 - porridge

Teatime around 3 - 4pm - 210ml formula milk

Dinner around 6:30pm - porridge

Before sleep at night around 9pm - 210ml formula milk

Here are some photos of a sample lunch+dinner portion that I'm cooking for her daily:

Yesterday's lunch and dinner : half a sweet corn + 1 tomato + half a zucchini + around half cup of rice, boiled with anchovies broth





This is the portion she would take at lunch and dinner each.

Other combination of her porridge are like:

1 sweet potato + some cawliflower + half sweet corn
chicken fillet (minced) + 1 sweet potato/potato + 1 tomato
1 carrot + some cellery + tomato + pumpkin

etc etc...

Then she will drink about 100ml of cool boiled water a day . And sometimes, she might take some snacks between meals, like two pieces of rice crackers, and sometimes a piece of fruit after dinner.

So, is she eating healthily? Or am I feeding her too much food?
