Family time!

Kate Middleton's hospital stay has been made more pleasant with frequent bedside visits from her adoring husband Prince William along with her worried family, and Breaking Celebrity News has photos of Kate's brother and sister's sojourn to see their pregnant sibling.

Pippa and James Middleton stopped by the hospital in London Wednesday, two days after Kate, 30, was admitted for hyperemesis gravidarum, a severe form of morning sickness from which she is suffering.

Smiling for the cameras, the siblings were photographed entering the hospital as they headed to visit with ailing Kate, who is pregnant with the baby that will be England's third in line for the throne.

Later in the evening, Kate's mother, Carole Middleton, also visited her daughter in King Edwards VII Hospital.

As Breaking Celebrity News previously reported, security at the hospital has been heightened following an embarrassing incident when Australian radio DJs prank called pretending to be Queen Elizabeth enquiring after the health of "her granddaughter" and managed to fool an unwitting nurse.
