When you decide to wean your baby from a stainless steel bottle to a cup, a variety of techniques can make the transition easier on you both.
Offer your baby a cup instead of a bottle, and follow his cues. He may seem interested and may drink from it properly; if he has trouble or just refuses, try again in a few days.
Make a family policy that your baby can't walk around with his drink or play with his vacuum bottle. This will make it clear that he needs to eat at regular meal and snack times, rather than always holding on to the bottle. Follow similar rules yourself so you don't send mixed messages.
Substitute other things that will comfort your baby if he seems to be using his bottle as a pacifier. These should include extra attention and affection, as well as special games, toys and books.
If your baby gets thirsty at night, keep a spillproof cup of water nearby and offer it to him in lieu of a bottle when he wakes. The nighttime brandy glass bottle is often the most difficult to lose, but doing so is important. Using formula, milk or juice at night harms your baby's dental health, as the liquid will pool in the mouth, coat the teeth and lead to severe decay. Bottles also pose a choking hazard.
