It must be nice for Beyonce Knowles to have little sister Solange to help guide her in the baby department. Or – better yet – to call up People magazine and tell them how much more she knows about babies than her older sister. That tends to happen when you have a kid at 17. Solange had her son Daniel Julez, 3, while managing to stay mostly out of the media’s spotlight. She says that she’s left Daniel with Beyonce for a weekend a few times, and her older sis had no idea what to do.

First came Crazy in Love, then came the hush-hush marriage – could the baby carriage be far behind?

“Whenever Beyoncé decides to have a child, I definitely think she’ll be banging on my door,” younger sister Solange Knowles tells PEOPLE. In fact, when it comes to kids, Solange – single mom to 3-year-old Daniel Julez – claims Beyoncé has a lot to learn.

“She’s kept my son over the weekend,” says the 21 year-old singer and actress. “She’ll call me like, ‘How do you get this stroller out? And what about the car seat? I don’t know how you do this!’ And I’m like, ‘People do it every day.’ “

Solange refused to confirm or deny whether Beyonce and Jay-Z got married this weekend, insisting that “You’d have to ask them.” Isn’t a lack of a denial pretty much the same thing as a yes in this case? It’s utterly ridiculous. If nothing else, Solange said she wouldn’t be dolling out any marriage advice. She got married at 17 to her son’s father, and was divorced by 20. At this rate, I could see Beyonce popping out a kid and refusing to confirm or deny a birth.
