Corrected entry: In the episode where Rachel comes home from the hospital, she and Ross realize they forgot diapers. Ross goes out to get them, and a muffin for Rachel. Soon after he closes the door, Emma starts crying. A little while later, they come back to the scene, and Emma is still crying. Phoebe said Emma had been crying a few hours. They jump to the scene where Ross is getting Rachel's muffin. He had just gotten back from getting diapers. It took him a few hours to go get diapers?
