Former Miss South Africa Jo-Ann Strauss shared a heartfelt message with her newborn daughter on Instagram, saying: "You've got this."
Jo-Ann and husband Michael Held welcomed their fourth child together in October.
Sharing a photo of her newborn, and her older daughter as well, she wrote: "One day I'll tell you that you were born in a year in which the world felt like it turned upside down, but when you arrived in our family, you helped put everything into perspective."
"Almost three weeks since she arrived ... how time flies and drags at the same time. Last night was a night where sleep and I didn't manage to coordinate our times. I did the school drop off with unbrushed teeth and hair and it's all ok. Now into board meetings - thanks goodness for online meetings where I can switch off video," she added.
Jo-Ann went on to say "don't sweat the small stuff," and encouraged her daughter to focus on the bigger picture. "You've got this," she wrote.
The TV presenter and model also shared a message with her three older children, saying: " [I'm] super grateful to my older kids for being the most incredible babysitters."
