2. The baby may be scratched by such bottles if there are cracks. It's even more dangerous if you use glass bottles.
Mothers need to check their baby's pacifiers regularly, at least every two to three months, to see if there are any breaks or cracks as follows:
1. Breast milk or formula pours out of the nipple. Normally, milk should drip out slowly from the nipple. If it flows very fast, it means that the nipple hole is too big and should be replaced.
2. Pacifier discoloration, which may indicate that the pacifier aging.
Generally speaking, if the bottle is used reasonably, the probability of the above two situations is very small, especially the glass bottle. If it is used properly, there is no need to replace it at all. If the plastic bottle is used properly, mothers can check it every four months or so. If the above situation exists, it should be replaced in time.

3. The nipple becomes thinner, which indicates that the nipple is beginning to be weak. The way to check the strength of the nipple is to pull the nipple hard. A good nipple should bounce back to its original state. If it doesn't bounce back, it shouldn't be used again.
4. Pacifier stickiness or expansion, which may also be caused by pacifier aging.
5. Pacifiers are cracked and damaged. In case of debris falling, it may suffocate the baby.
