Beyoncé is a "very involved" mother to her brood.
The 36-year-old musician has daughter Blue Ivy, six, and twins Rumi and Sir, seven months, with her husband and rapper Jay-Z, and although she is often busy with her successful career, she makes sure to spend plenty of time with her brood.
A source said: "Beyoncé is spending a ton of time with her twins and is a very involved mom."
And even when the ‘Halo’ singer does have her hands full, big sister Blue Ivy is always on hand to help her mother look after her younger siblings.
The insider added to Us Weekly magazine: "Blue loves the twins and is always checking on them and helping out with mommy duties."
It isn’t the first time Blue Ivy has been labelled as a fantastic big sister to her two younger siblings though, as when the twins were first born, sources revealed Blue was "serious" about being a protective older sister.
A source said at the time: "Beyoncé has been very busy with the newborns, but she’s also been able to relax a bit. It’s helped her that Blue has been such an amazing big sister.
"There was no need to worry because Blue is great. She takes her job as a big sister very seriously and helps out a lot."
Before the babies arrived, the ‘Crazy in Love’ hitmaker ensured her focus was on Blue and "made sure to spend lots of quality time" with the youngster.
The family recently splashed out on an $88 million mansion closer to their oldest child’s school and Blue couldn’t wait to see her friends in kindergarten in September.
The insider said: "Blue is excited about starting kindergarten. She misses her friends. It will be fun for her to get back to her own life at school. Beyoncé is excited for her too but keeps saying that she can’t believe Blue is starting kindergarten. She thinks Blue is growing up way too fast!"
