Samantha Milk

This summer Andrew has not wanted to drink his milk. One morning I came up with the story of Sam (Samantha) the cow that comes to our house every morning to deliver her fresh milk.  She calls Lily and Andrew on Lily's play kitchen phone to ask if they liked the milk and if they want milk for tomorrow.  Well Andrew has loved this story and most days guzzles his milk down at breakfast and then races to call Samantha to tell her that he drank all her milk up. Today it was raining so I told them how Samantha had to get wet delivering our milk this morning :)  We have been calling Samantha for about a month, I wonder how long she will be delivering our milk?
