Love is in the air!
Kim Kardashian West‘s Instagram feed has been full of bikini selfies and topless shots lately — but on Wednesday, the reality star switched things up, dedicating a sweet post to her husband Kanye West in honor of Valentine’s Day.
“I love you to infinity! Happy Valentine’s Day!!!” she captioned a paparazzi photo of the two from their trip to Paris in March 2015, with West, 40, wrapping both arms around Kardashian West, 37.
West returned the favor, returning from an Instagram hiatus to wish his wife a (very minimalistic) “Happy Valentines Day Babe.”
“He said that being a dad is what he does best,” the source said. “He does everything that a dad does. Even diaper duty. Kanye knows how to change a diaper, 100 percent! That’s very important to him.”

The source also told PEOPLE that West credits his children with helping him through trying times. The couple had a traumatic year in 2016 — Kardashian West was robbed in Paris; he had a mental breakdown. But after learning they were expecting a daughter, they entered a happier stage.
“Kanye says that his children have saved his life,” the source said. “This one in particular came along after a very dark time. He’s so in love with his kids.”
