The 36-year-old model - who raises four children Leni, six, Henry, four, Johan, three and seven-month-old Lou with husband Seal - admits she worries about her weight and appearance, but doesn`t think her concerns are anything out of the ordinary.
She said: "We all have the same issues. Every woman. It`s thighs, butt, arms, muffintops. All those fun things, we all have the same issues."
The `Project Runway` host also revealed that her family like to make personalised gifts and cards to mark special occasions.
Speaking about forthcoming Father`s Day in the US, she told Hollywoodlife.com: "Probably we`ll do something fun like the children will maybe draw something or make a poster or a painting or something. Usually we do arts and crafts."
Heidi - who has two maternity lines, Loved and Lavish for A Pea in the Pod - has encouraged pregnant women not to lose their sense of style when they are carrying a baby.
She said: "It shouldn`t change when you`re pregnant that all of a sudden you have to wear a moo moo and call it a day."
