I am fairly certain Sass has this. It started showing up around 6 months when we started solids. I looked back at her old pics and I am thinking thats what it is. It makes sense....she eats a ton of orange vegetables. Luckily it is nothing serious, and all the orange veggies are good for eye and brain development, so I am not worried about it. I just noticed her poor little nose is orange and she now just has an orange glow about her. Here are a couple pics to show the difference.
The first two are of Sass prior to eating solids...notice her nose is the same color as the rest of her face.
These are recent pics of Madison, notice the orange color on her nose is more noticeable.
