Yippee!! 7 m. old finally sleeping allnight. Is it the chicken?

I gave my 7 m old (she'll be 8 months this Friday) homemade chicken puree along w/ veggies and applesauce for dinner on Saturday night and she slept through the night for the first time in her life. I continued the chicken w/ dinner on Sun. night and she did it again. Is it the chicken or just a coincidence? Im so excited!! Sleep finally!!
