I'm needing some advice on when to start my 5month old baby girl with a sippy cup. At her last WIC appt, they told me to introduce the sippy cup at least by 6mos. They said that the baby prob wont be able to hold it or know what to do w/ it but to let them practice. I was told to put breastmilk or formula in the sippy. When I asked if that was kind of early, they said that if I wait too long that it could make it tough to wean her from the bottle later. When did you start giving your little one a sippy to practice with? Did you start w/ the soft tipped or hard tipped ones? Thanks!
