I just looked at DS's face and he has a bite on the side, by his left eye. It's a white bump surrounded by red. Looks like either a bite or a random hive. The window is open but maybe something flew in like a mosquito or maybe it's a spider (he was rolling around on the floor). He's not obsessively scratching, is there anything I should do for it or just let it be? He's 14 months.
