E.B.
With my two older kids (now 6 and 7) we used the gerber started cups (handles on both sides) and small to grasp. We started them on cups abotu the age of 5 months. I didnt want a spout that was hard so I got the gerber ones that have the rubber over them. My kids also liked the straw cups after that. With my youngest now 3 and half months Im going to start her with either the gerber or straw. After they are older Id go to the playtex hard spout ones.
Best of luck!
