Mandy Moore hasn't let becoming a new mum hold her back from adventuring.
The This is Us actress, who welcomed son August (Gus) in February, is back climbing mountains - breast pump in hand.
Sharing her latest adventure with fans on her Instagram stories, the 37-year-old took on Mount Baker, in Washington (state) with friends.
Moore, who said she had to wake up at midnight for the sunrise adventure, said it had been an exhausting endeavour.
"We made it. On the summit at 6:30 this am. More to come. Never been this tired. And I have an infant," she captioned a photo of herself at the peak.

What was more impressive than the climb though, was that she managed to fit in a few pumps along the way.
In one pic, Moore shows herself sporting a portable manual hand pump, captioning it: 'The new realities of adventuring'. A second pic shows her pumping again at the summit.
"I have an oversupply of milk. If anything, that's been something that I've been dealing with, but I'm sure it will regulate itself and be fine down the road," she shared.
"I have a lot of milk, and so his feedings are not super long. He gets plenty in eight to 10 minutes," she continued. "... Sometimes he doesn't get to go to the other side during a feeding because he gets plenty of milk. But yeah, it hasn't been a huge issue. I've had to pump a couple of times just for relief and just to help get rid of some of the supply, but I'm storing it."

After returning to work on This is Us in April, however, Moore did experience a painful blocked duct from pumping and feeding on set.
"Definitely doing football holds and exclusively nursing on the one impacted side, lecithin, massage, hot epsom salt baths, etc," she said on Instagram at the time. "I have a suspicion it's from being back at work and pumping more often then having him on the boob during the day. ALL good!"
