poopy has 2 different sippy cups, one for water and the other for milk. he knows which is for which, and takes the one he feels like drinking. when he wants milk he will reach out for the milk one. when we are out, we fill up the milk one and take water as well. and he will go for milk when it's his milk drinking time.
was just thinking maybe have 2 for mj, in case she doesnt want her milk, she doesnt completely stop associating the sippy cup for water. dont want her to think her water cup is now a milk cup and not want it anymore...
