London, Dec 1- German supermodel Heidi Klum has revealed she is finding it tough having four children.

The supermodel - who gave birth to daughter Lou last month - is struggling to adapt because her newborn baby demands a lot of her time and attention which her other three kids don't understand, reports fametastic. co. uk.

"Of course this is all very tough for me at the moment because Leni, Henry and Johan want to continue to do things with their mama and papa. They are not really interested in the fact that you have just had a baby. Seal (her singer husband) and I have a lot of work because we have to divide everything among us. But it's great! We are incredibly happy and the family really satisfies me," she said.

"At the moment Lou needs me enormously. Not only because of breastfeeding but also because she needs to be close to her mother. She will sleep now for a year with us in our bedroom - just as her siblings did. It's easier at night if she is hungry," she added.

The 36-year-old beauty keeps her other children - daughter Leni, five, and sons Henri, four, and Johan, three - happy by making sure they're kept busy.

"You must always think of new things - this is sometimes a challenge. We often make play dates with other kids or we go to the park. On weekends we like to go to Disneyland," she said. (dpa)
