Kate Middleton Depressed? Sources Say Duchess Kate Struggling With Postpartum Depression Amid Tension With Queen Elizabeth

Kate Middleton may be battling depression as she makes the abrupt adjustment to life with two young children, sources close to the royal family indicate.

Duchess Kate has been spotted spending time with her kids lately, including a trip to the park with Prince George, but sources indicate that the hectic life of raising two kids under the age of 2 has been wearing her down.

Some hints of that came out in the People magazine feature story about Duchess Kate and her growing family. The story quoted royal photographer Mark Stewart, who said that Prince George is "a handful – a live wire." Now, Celeb Dirty Laundry is reporting that the hectic life is sinking Kate Middleton into a bit of a depression, which has caused tension within the royal family.

"With Kate Middleton's royal revolution, breaking traditions to raise the children herself with a family focus, it appears she is starting to feel the pressure. A previous report stated that the exhaustion is coupled with some depression. According to other royal sources, Kate is also battling postpartum depression. Despite the exhaustion and rumored depression, Kate continues to make changes and raise the children with middle class values.

Queen Elizabeth isn't happy about the break in royal protocol, and has made it clear she wants to see Prince George and Princess Charlotte raised with royal values. The entire Middleton middle class revolution angers the Queen, who constantly butts heads with Carole Middleton. However, Carole isn't backing down. Kate's mother has allegedly moved out of Anmer Hall, after staying to help the Duchess after she gave birth to Princess Charlotte, but still checks in with her daughter on a regular basis."

There may be other pressures, as well. While she's facing the pressures of two young children, Kate Middleton has also been very focused on dropping her baby weight. The Duchess was spotted in the last week wearing skinny jeans and already appears to be back to her pre-baby weight.

A source told People that Kate has been working with an elite trainer, one who has a stable of A-list clients, including other royals and big-money executives.

"It's a lot of money, but you get a lot for the price," the source said.

"The trainer checks in remotely with Kate by phone every day as well as seeing her in person once a week," the source added.

If Kate Middleton is battling depression, it may not be that unusual. Health experts estimate that as many as as 20 percent of new mothers suffer some level of postpartum depression.
