It's a role that can sometimes go unnoticed and unthanked — but one father's heartfelt tribute to his stay-at-home wife has struck a chord with other parents.
US dad Zack Williams shared a photo of his steamed-up shower door in a Facebook post, writing that he had noticed the baby's bassinet was in the bathroom after going in there the day before to clean up after a 12-hour day at work, reports news.com.au.
"I asked my wife if she had put her in there, and how she did in it. She said she put her in it as she had showered during the day," Mr Williams wrote.
The next day he was about to shower and noticed his glass shower door had a part that had been wiped.
"I literally just sat there and stared at the glass and smiled. I could see it, I imagined it, it was like I was there in the room with them," Mr Williams wrote.
"I could see Heather just looking through the glass and making faces at Lottie as she smiled and played in her bassinet! I just melted!"
Mr Williams said the realisation had made him "so appreciative" of Mrs Williams, as it made him realise all the "little sacrifices" she did "would normally go unnoticed".
The idea that Mrs Williams should be responsible for the entire household because "all she does is have to take care of a baby" while he works was wrong, he argued.
"The fact that my wife can't even shower without caring for someone else; tending to someone else's needs. She doesn't get a second to herself to relax," Mr Williams wrote.
"My wife doesn't get to clock out, my wife doesn't get the satisfaction of seeing a cheque deposited in the bank in return for her hard work, my wife doesn't get to eat lunch with co-workers, my wife doesn't get to just walk outside and just take a deep breath.
"This may be just a fogged-up piece of glass to some, but to me it means so much more. It's the little things like this that don't go unnoticed.
"It's the little things like this that constantly remind me how badass she is. It's the little things like this that make me fall in love with her all over again, Heather Williams!"
Mr Williams' post, originally shared in September, was reposted by fatherhood blog His View From Home on Facebook where it has been shared more than 27,000 times.
It's also attracted thousands of comments praising the "crazy" levels women must go to when they're a stay-at-home mum.
"That's beautiful, I remember many times doing the same thing. There's never a moment to yourself when there is a little person wanting all of your attention," one person wrote.
"Thank you for realising what we do! I did this with both of my kids. I was never alone," said another.
"I'm fortunate enough to be a full time mom but I wish my man appreciated me this much. He doesn't necessarily not appreciate the work I do for our child and home but I never hear it and it would be nice to."
