Clogged nipple

My poor Squirmalicious!  She is a very slow eater and grazes all day but today she seemed to be eating for 15 minutes at a time, spitting the bottle out and occasionally burping or tooting but her bottle was never empty.  Now, she has discovered her tongue and is playing with it while eating but it was starting to seem like we had a miracle bottle that always had milk.  I know breast milk is amazing but this was crazy.  I finally realized that the nipple was clogged.  Now I'm thinking poor baby, she must be starving!  Filled another bottle but she only ate about 2 ounces, then burps and a grumbling belly along with some fussiness.  Her belly must have still been bothering her after giving her Mom a vomit shower the night before.  Only ate another half ounce and fell asleep for an hour and a half, mostly in Grandma's arms before Daddy picked her up.   It's so sad to see her not feeling well.
