Kate Middleton is due in a few weeks, but the royal is still busy with work.

In September, the palace announced that the Duke and Duchess of Cambridge are expecting their third child. The couple will welcome the new addition to their family in April. It's already March and Middleton has still a number of scheduled events on her calendar.

Middleton still has two scheduled engagements. On Wednesday, the Duchess of Cambridge will visit the Place2Be's new headquarters in London to officially open it. The charity's new headquarters is equipped with state-of-the-art facilities to allow the organization to train more counselors, teachers and school leaders to provide emotional and therapeutic support to schoolchildren.

In addition, Middleton is expected to join Queen Elizabeth, Meghan Markle, Prince William and Prince Harry at the Commonwealth Day on March 12. In fact, the fab four is expected to visit the square behind the Abbey to meet the school children before attending the reception.

The engagement might be Middleton's last before she welcomes her third child. If so, then the new addition to the Cambridges might arrive early April. However, if Middleton will still carry more engagements towards the end of the month, then her baby might be due end of April, Daily Express reported.

Prince William's wife just had her busiest start of the year. In fact, she already completed 38 royal engagements to date.

Grant Harrold, Prince Charles' former butler, explained that it's not surprising to see Middleton still at work as her schedules are planned many months ahead. Also, the Duchess is expected to take a break after her delivery, so it is likely that Middleton is taking more jobs to make up for the schedules she has missed or will probably miss.

"The Duchess will, of course, be having some family time once she has a third child and it is unlikely that she will be seen for a few months after the birth of the next royal baby," Harrold explained. "It is most likely that she will be trying to fit in as many engagements as possible before the due date, and make up for the time she was unwell and unable to attend some of her previous events."

It can be remembered that Middleton was suffering from hyperemesis gravidarum or severe morning sickness in the early stages of her pregnancy. Her condition forced the Duchess to cancel some of her engagements at that time.
