Kate Middleton's morning sickness has reportedly gotten so bad that the Duchess of Cambridge went back to her parents' house for comfort.

The 32-year-old visited her family home in Bucklebury, Berkshire, with Prince George this week as she deals with her hyperemesis gravidarum, which forces her to vomit several times a day.

"Kate is feeling so lousy that she just wanted to be with her family and out of public view. She is extremely close to Carole, who is very much a hands-on grandmother. Between her and their nanny, Maria, Kate has all the help she needs with George while she is feeling so sick," a source told the Daily Mail. "And Bucklebury is somewhere she can just relax and be herself."

The Duchess has also been forced to cancel several appearances after it was announced in September that she was expecting her second child with husband Prince William. It's unclear if she will be able to visit the president of the Republic of Singapore on Oct. 21 as expected.

Middleton suffered from the same condition during her first pregnancy; however, she's "being treated by doctors at Kensington Palace," a royal announcement revealed last month.

"Don't be fooled by the fact that she hasn't been admitted to hospital this time. She is just as poorly. The difference is that her doctors have been able to diagnose and treat her quicker. She really hasn't been at all well, though," a source also said.
