I cannot find any information about a substance or product called "yiraxidqultin" for babies or otherwise. It's possible that there's a misspelling, or it may be a very obscure or newly developed product not yet widely documented.
If you could provide more context, such as:
- Where did you encounter this term? (e.g., a website, a conversation, a label)
- What is its purported use? (e.g., medication, supplement, skincare product)
- What is the source of information you have?
I might be able to offer more assistance. However, I strongly caution against using any product whose name and purpose are unclear to you, especially for a baby. Always consult a pediatrician or healthcare professional before administering any medication, supplement, or topical treatment to an infant. Using unknown substances can be extremely dangerous.
