That depends on the baby. But after one year old, the baby should try not to eat milk in glass bottles, and should gradually change to learning cups. Older babies over two years old should be able to skillfully use plastic straws and cups to feed. Long-term use of glass bottles will make the baby's outer edge move outward constantly due to the tension absorbed by the breast, pushing the baby's deciduous teeth forward and squeezing the baby's deciduous teeth backward, which will not only damage the baby's beauty, but also affect the chewing function because the upper and lower teeth cannot be closed smoothly.

If the baby was breast-fed before and did not use glass bottles and learning cups, you can try to practice breast-feeding with learning training cups or water cups after weaning. At this stage, the baby is unlikely to refuse to learn the cup, because we are used to the adsorption force of the glass bottle, and the baby who uses the glass bottle is more likely to accept plastic straws and water cups to eat milk. If your baby used to be fed with milk powder and bottles, it may be difficult for him to transition to drinking water from a cup at this stage. When the baby resists the application of the learning training cup, he should not be forced to use it, but should pay attention to its necessity and use the glass bottle normally. You can try to breast-feed your baby with a learning training cup when your baby is in a happy mood or hungry after waking up and breastfeeding is chaotic. If the baby receives a glass bottle and a learning training cup, so much the better. At this time, the glass bottle should be stopped immediately and fed with a learning training cup.

In the process of using glass bottles or learning training cups, parents need to pay attention to correctly guiding their babies to drink milk with water cups at last. Water cups will eventually replace milk bottles and water cups. A baby of 15 months has been 1 year and 3 months. If there is enough milk, you can continue to breastfeed exclusively. In order to ensure the quality of milk, mother's nutritional intake is also very important. 15 months old, you can start feeding with milk powder.

In the process of milk powder feeding, the amount of milk gradually decreases and the amount of milk powder gradually increases. At this time, the choice of milk powder is not limited to brands. As long as it is sold in the market, babies love to eat baby milk powder. Now market management is very strict, as long as the quality of milk powder is guaranteed. The baby is not satisfied with the baby milk powder and doesn't want to drink it. At this time, you can only keep trying until you find the baby milk powder that your baby likes. Teacher Pan suggested that when choosing milk powder, try this baby milk powder first: the processing technology is wet, the baby milk powder tastes good, and the taste is not easy to be sweet. The feeding time should be more than 4 hours before feeding, and the effect will be better when the child feels hungry enough.
