The 'Keeping Up with the Kardashians' star says it's ''remarkable'' to watch Kim, 33, take dote on North, her seven-month-old daughter with fiancé Kanye West.
She said: ''She's changed, in a really good way. You watch your baby have a baby and it's kind of remarkable to see the changes we all go through when you give birth and have a child you're responsible for.
''Kim's totally in love with North, it's been wonderful to watch.''
Kris, 58, also revealed that Kim is a very hands-on mother and hates handing her little girl over to anyone - even her.
Kris added: ''She really is hands-on. I'm always like, 'Can I hold North now?' and she's like, 'Mom, please.' Because all she wants is to hold her. She loves that baby so much.''
Kris is overjoyed that Kim - who has previously been married twice - has found happiness with Kanye and thinks they are an ''amazing'' couple.
She told Britain's OK! magazine: ''Kanye and Kim are an amazing couple. They're very much in love and have the most delicious little baby. The dynamic has been a blessing. Kanye is the greatest and has been so awesome. Life at my house is pretty dreamy, there's a lot of love there.''
