Tina Knowles is open about the sometimes difficult childhood of her daughter Beyonce.

On Sunday, 5/26, Knowles shared a video of a recent interview with Vogue on her Instagram page where she discussed her favorite memories of her children Beyonce, Solange, and the honorary third daughter, Kelly Rowland.instagram.com/Kelly-Rowland/Kelly-Rowland/Kelly-Rowland/Kelly-Rowland/Kelly

"Beyonce, she was so shy and a little bullied, but the day she stood up for someone — she stood up for herself." I could not be more proud of her.

Knowles also recalled the moment his daughter, Solange, "was singing a petition at school."

"She was only like a fifth grade, and she had me sign a petition," Knowles explained. "So she was always an activist.

Knowles said that her honorable 3rd daughter Roland "was this child who always tried to protect everyone."

"I have her memory that with her best friend Barbara she is an intermediary and just the one who makes this little peace," she adds.

Knowles also added a moving caption to the nostalgic post, saying that "Each child is different" but that they "all have different personalities." It reminded us that it's so special."

"I believe that children are born with their individuality. All my 3 girls treated things very differently," she wrote. "Learn their individuality and respect their individuality. Do not compare the negatives, always praise the positive differences and pay attention to what you can boast about them. They love it and it encourages positive behavior.

Now Knowles is not only a proud mother, but also a proud grandmother of 4 who is making new memories with her daughter's children.

Beyonce is the proud mom of 3 daughters Blue Ivy, 12, and twins Rumi and Sir. Solange is the mom of 19・year・old son Daniel Jewel's Smith Jr., who she shares with ex・husband Daniel Smith.

"It's the best. With grandchildren, you don't have the pressure to be responsible for how they turn out, so you can pamper them and let them have a noisy toy that drives their parents crazy," Knowles said during a recent appearance today with Hoda & Jenna "It's just the best." They are the best. My grandchildren are all super creative and I just love them until I die."
