It's important to follow the specific height and weight guidelines for the booster seat to ensure the child's safety. **

Seat reservations can be beneficial in certain situations, such as ensuring that groups can sit together or guaranteeing a specific seat with extra legroom. However, in cases where the train is not crowded or there are plenty of available seats, a reservation may seem unnecessary. Ultimately, the usefulness of a seat reservation depends on individual preferences and circumstances. **

It is generally not possible to travel earlier than the time specified on your seat reservation. This is because seat reservations are made for specific train or plane departures, and the transportation company needs to ensure that all passengers are accounted for and that the vehicle is not overbooked. If you need to travel earlier, you would typically need to change your reservation to the earlier departure time, which may incur additional fees or charges. It's always best to check with the transportation company for their specific policies on changing reservations. **
