Mystery Eye

What happened to his eye???

I can't stop cringing and feeling so bad for little Ammo every time I look at him!
The poor thing!!

I was subbing in Nursery yesterday so I had Ammon with me. About half way through nursery he was sitting on a Sister's lap when I noticed his eye looked smaller...swollen...and weird looking! I asked her if she could tell and she said it did look a little swollen.

Is it a black eye from nursery that I didn't see happen and he didn't cry after? But it isn't black and blue... just pink?
Is it pink eye? But there is no goo or anything.
Is he allergic to something that would make just one eye swell like that?

Awe, what happened to my poor baby?

Side note: Ammo's eye apparently is drooping significantly. Marek thinks he is permanently sad.
