My 17 mth old has a small black eye..he is a twin and my boys are starting to play rough..he hit his eye on his toddler bed ..eye is not puffy just slightly black on the bottom..he has night been irritated..I am a first time mom and I'm afraid that when I take my boys to daycare tmro that the teacher may think I'm abusing them...
