The Little Couple stars Jen Arnold and Bill Klein, who renewed their vows in April, know the secrets to a happy marriage, and they shared them with PEOPLE Now on Thursday.

Klein’s tip for maintaining a strong relationship is not to go to bed angry.

“We, like everyone else, have arguments, but we don’t let it go to the morning,” Klein tells PEOPLE NOW. “Everything is resolvable, even if someone has to say they’re sorry.”

Arnold’s three rules: knowing when to give in, the wife is always right and the importance of making time for each other. They have their hands full with their two children, Will, 4, and Zoey, 3, but they don’t let that get in the way of spending time together every day.

“When you have a busy life, particularly two toddlers that can take up all your attention and energy during the day, so you make sure to have something at night,” Arnold says. “It could be a glass of wine after you put the kids to bed, watching a TV show, making sure you give at least 10-15 minutes of your time to each other.”

The couple also makes sure to give their children, who both have forms of dwarfism, the same attention they give each other – so they want to wait before adopting anymore kids.

“Right now, we’re really happy,” Arnold says. “I love giving them attention and being able to spoil the two the way we’re spoiling them. At some point, they’re going to not like us, like every preteen, and at that point maybe we’ll be ready for a third.”

They also don’t think it would be “out of the ordinary” to adopt a child without dwarfism.

“Our original goal was to use our experience as little people to maybe help out kids who were in a similar circumstance and were looking to build our family, so we thought that was perfect,” Arnold said. “But, there’s a lot of kids out there that obviously need a good home and we have that.”
