Do I need to make an appointment for a visa extension at IT Square Laksi office, and how many appointments are necessary for my family?

The user inquires about the necessity of making an appointment for a visa extension at the IT Square Laksi immigration office for themselves, their husband, and their baby. They ask if multiple appointments are needed and seek advice on the best time to visit if no appointment is required. A commenter suggests going early in the morning or around 3 PM, noting that since the baby does not have an overstay, there's no need to apply for anything additional.
