The cup I bought because it was recommended by the playgroup leader and a number nursing course ordered. The child learns to properly drink and mainly concentrated to drink. The harmful continuous sucking is not an issue with the cup. The cup contains a groove for the liquid targeted to carry in your mouth. The shape of the cup is optimal - the baby / child can grab the cup very well with both hands. Pimples on cup rim help trigger the swallowing reflex. Drinking the cup but must be practiced. The baby needs to understand only that it can drink without sucking (as at the breast / bottle). Since the 5th month I practice with our little drinking by giving some breast milk into the cup. The milk she knows - that facilitates the exercise drink. She has a lot of spilled The first few times, because the tongue reflex is still there (child transported food out of the mouth) and she wanted to suck. With a bib is over no problem. She enjoys the daily drinking and exercises umfass the cup with both hands properly. But it is getting better every day and works now correctly gut.Absolute buy recommendation !!!
