What's the best way to transition to a sippy cup?
Some babies take to a sippy cup immediately, while others take a while to get used to the idea. Here are some tips on making the transition easier:
Start off with a soft, pliable, nipple-like spout, which will feel more familiar to your baby than a hard plastic spout.
Show your baby how to raise the cup to his mouth and tip it up to drink.
Give it some time. Until your baby masters the technique, you may want to put water in the cup to avoid too many messes. Don't worry if your baby doesn't use the sippy cup properly for a while. It makes a fine toy, too!
Try different models until you find one that suits your baby. Some cups have valves that are so effective at keeping the liquid from spilling that children really have to work to get a drink.
From what I remember with my son, he was about 1 1/2. My nephew just turned 2 yrs. old & he only uses sippy cups & regular cups (he hasn't had a bottle in a couple months.)
