Singer John Legend is his wife's biggest fan, but he's revealed how he wasn't "emotionally prepared" to deal with her postnatal depression (PND).
Like many partners of women with PND, Legend said it was confusing to see Chrissy Teigen so unhappy following the arrival of their beautiful baby girl Luna.
"You don't see it coming," he in a column in The Sun.
"You're not emotionally prepared for someone that's going through a dark time as you're welcoming this new life.
"When you don't understand what's happening, it's a bit challenging to figure it out and you don't know if it's something you've done or some other reason why she's not feeling well.
"Once you understand what the reasons are then it makes perfect sense and you can adjust accordingly.
"It's a chemical thing that happens to a lot of people after giving birth and there are ways to treat it and deal with it."
He praised his wife for speaking openly about her own struggle with post-natal depression.
"So many people go through this – they say one in nine but there's probably more than that," he said.
"I think it was good for her to talk about it.
"She was coming out of it and was able to see it more clearly with some perspective and I think it was helpful for her to be on her way out of it as she was writing."
Teigen recently shared an open letter detailing her struggles with post-natal depression after the birth of their first child Luna. She explained how things got so bad she went to her doctor.
"I looked at my doctor, and my eyes welled up because I was so tired of being in pain," she said.
"Of sleeping on the couch. Of waking up throughout the night. Of throwing up. Of taking things out on the wrong people. Of not enjoying life. Of not seeing my friends. Of not having the energy to take my baby for a stroll.
"I look around every day and I don't know how people do it. I've never had more respect for mothers, especially mothers with postpartum depression. I'm speaking up now because I want people to know it can happen to anybody and I don't want people to feel embarrassed or to feel alone."
The family is about to head off on tour, but there's more than just music on his mind.
"We want three or four children," he said.
"We're still excited to have more kids and we're going to do it."
The couple's openness about their experience will hopefully help others who are struggling to seek help – to see through their seemingly picture-perfect life.
