DS does this too. DB was worried about it but I kept telling him it's (probably LOL) normal. DS will sometimes ask a question (or make a demand) 5-10 times in a row, even after we answer him. I find that if I answer with a "mmm hmm" kind of attitude he does it more. This morning he said "me go grandma linda's house" about 15 times. He finally stopped when I said, "yes, we are going to grandma linda's house!". I figure it's just an extension of his colicky persistence.
