Girls, what could it be? The baby has something like specks, he's snuffling his nose. I was trying to clean with aqua-marigold, sucking out with an aspirator (nothing is coming out), I clean every day from little dust bunnies ?. It seems like the nose is clean, but it looks like there's something inside, like a speck somewhere.
