My baby is 2 years 7 months but still Yalu is not filled. She is healthy and has achieved all the milestones of her age. Also the Yalu is lil turned inside

A. Yalu as in the head sink that you are talking about that little bit of dent is there in the head if that is what you’re talking about then if it hasn’t filled by the age of 2.5 years also then in that case you can take an assistance with your doctor regarding that but you are the good part is that your child has achieved all the milestones is healthy and active so I don’t think so there’s anything to be worried in this
