Kudos to Kim Kardashian! The Keeping Up With the Kardashians star, 38, is doing an amazing job raising her four kids and making sure none of them feel left out. Thanks to her, her second child, Saint West, is pretty involved with helping take care of newborn, Psalm West.

“Saint loves nursing Psalm, with the help of Kim of course!” a source exclusively revealed to Life & Style. Though he enjoys being involved, right now he likes to spend most of his time with big sister North. It’s not totally surprising since they are closer in age — Saint is 3, while North is 5.

“He’s only 3 years old and is more interested in following his big sister around than the baby. I’m sure that will all change once he’s a bit older,” the insider added. Saint isn’t the only family member who Psalm is slowly growing on. Kim and Kanye West’s youngest daughter, Chicago, is taking some time to adjust to not being the baby of the house anymore.

“Chicago didn’t really understand that she was going to have another brother until the baby was born, a source previously told Life & Style. There were some jealousy issues to begin with — she’s used to being the youngest and her parents doting on her, but she’s fine now and is adjusting well.”

On the other hand, North is doing great in her big sister role. Despite enjoying all eyes on her, she doesn’t seem to mind sharing the love with baby Psalm. “North always wants to be center of attention, which is why Kim’s making a huge effort to ensure her eldest doesn’t feel left out, especially now there’s four of them competing for her attention!” a third source exclusively revealed.

“She’ll let North pick out onesies and other cute baby clothes for Psalm to wear so that she feels involved, and has organized a no-expense-spared birthday party for her next month,” the source continued. So far there haven’t been any jealousy issues, North adores Psalm and treats him like a little doll.”

We can’t wait for Psalm to get older to see how all their dynamics will change!
