Why babies should use a open top cup?

Cups with lids so easy, less mess so what's the problem.Spouted cups and bottles promote a sucking action and it is recommended that from six months babies should start drinking from an open cup.The thing about an open top cup is that it develops the lip and tongue muscles a baby needs for speech. I hadn't realized that by introducing an open cup and stopping a bottle by age one I would be helping my baby to speak.Isn't knowledge a wonderful thing.Can't wait for those first words I'm sure it will make the mopping of spills worth while. The doidy cup has been great it is sloped so little ones can see the liquid and helps them not to tip all over themselves
