New Sippie cup
Our 18 month old has outgrown her sippie cup with handles, the rubber piece inside of it does not work at keeping it spill proof any more, and I can't seem to find it in stores. I bought it probably about 8 months ago. I just picked up a new type of sippie, but the suction needed is stronger and she doesn't want to make the effort . . . . how do i get her to use it? The new cups are bigger and no handles. She holds it just fine, but she gets mad when she puts it to her mouth and nothing comes out. What do I do to help her want to use it? HELP!!!
