Can a baby over 5 months old use a gravity ball baby bottle?

Generally, infants around five and a half months old should not use gravity ball bottles. The early use of gravity ball bottles is not recommended, as it may affect the infant's oral development. The detailed explanation is as follows:

The design of gravity ball bottles differs from that of standard bottles. A gravity ball bottle typically contains a small spherical weight at the end of the drinking tube, which moves freely within the bottle, allowing the baby to drink milk smoothly even when the bottle is tilted or held horizontally. When using a gravity ball bottle, it's important to regularly clean and replace the internal gravity ball. Infants around five and a half months old may lack sufficient hand strength and have not yet fully developed their oral structures. Using a gravity ball bottle at this stage may negatively impact their development; therefore, it is not advisable for infants of this age.

In daily care, it is recommended to choose high-quality bottles for infants to avoid health risks associated with inferior products. Additionally, proper cleaning of bottles is essential to prevent bacterial growth, which could otherwise lead to gastrointestinal discomfort in infants.
