Yucky Milk

Picked up Isaiah from daycare and he saw his milk cup that was left in his cupholder since this morning. Isaiah wanted to drink it but I said to him that its yucky milk now - look at it. He said "nnooooo! I need it!" I didnt want to fuss so I gave it to him...and he spit it out. The milk was curdling - you know when cheese starts to form...I dont know the word for it. Anyway - Isaiah learned his lesson and now its yucky milk. Duh!
