Drinking from an open cup seems difficult; but guess what? Babies can do it (when they are 6 months or older)! And it is also highly beneficial to them. First, you have access to open cups everywhere so when you go out you don’t have to be worrying about packing sippy cups. Drinking from an open cup helps babies develop a mature swallow pattern, master their mouth muscles and improve his motor skills and coordination.
Btw, sippy cups can lead to tooth decay because of the constant sipping wearing down the enamel and can also cause a delay in oral motor development. If you skip sippy cups together and teach your baby what he really needs to know you won’t have to worry about transitioning him from one to the other. Start by holding the cup for him and little by little get his hands involved until he is able to do it all on his own.
