If you're on a tight schedule, book the first appointment of the morning or afternoon, since it's less likely that your doctor's schedule will be backed up at that time. It's also worth considering your child's nap time and feeding schedule before booking an appointment. While many doctors have entertaining items in the waiting room, try bringing a favorite toy or book to occupy your child if the wait is longer than expected. Also, dress your child in something that's easily taken off and put back on, since that'll save time.
