Why did I give it to my picky eater?

My child is now 5 and old enough for kindergarten. I was concerned because they did not seem to be growing much taller than before, and I especially worried whether they were getting a balanced range of nutrients because they are such a picky eater.

My child has a small appetite and may even spit out food or snacks if they do not suit their taste. They do not enjoy outdoor activities, but they are active indoors and tend to get tired quickly. The product I started giving them after noticing these eating habits and daily patterns was The Day Our Child Strong Immunity Jelly.

What does the jelly taste like, and what does it contain?

It is a mango-flavored multivitamin jelly. Since it was for my child, I looked closely not only at the taste but also at what ingredients it contained.

In the product information, I saw that it contains vitamin D, B vitamins, and zinc gluconate. Because I am usually concerned that my child's meals are one-sided, this ingredient combination caught my attention.

Did my child with a small appetite eat it well?

My child asked for this jelly first. They held it in their hand and smiled, and told me the mango jelly was delicious.

When I tried it too, it was sweet and tangy. It contains mango concentrate, and it tasted good to me as an adult as well. The best part was that my child, who usually refuses foods they do not like, ate it well.

I took out one pouch a day. I only had to give my child one pouch rather than going through the process of getting them to take several things, and they ate it well on their own, so it was easy to give.

What did I check about the ingredients and additives?

Because it was a product for my child, I also paid attention to where the ingredients came from. The product information says it uses ingredients from Germany, France, Switzerland, and other countries, and does not contain synthetic flavoring or lactose.

I liked that I could look after my child with a jelly while also considering the vitamins. Above all, since my child ate it happily, I felt less pressure to persuade them to eat it.
