Engineered for mom, by mom.

Jillian Rothe is the mom, engineer, founder, and lactivist behind MILKworx (formerly MAMMaway). She founded the company in 2016 when she was busy working and traveling, but had limited freezer space and children to feed. She set out to find a way to store enough milk for her week-long business trips without the bags breaking in the freezer and going to waste, and that’s when she created Freeze It Flat™.

HAPPY PARENTS

“I’ve built up quite the stash over the holidays with little miss not going to daycare for two weeks… Having a stash, no matter how small, is important for me to have the reassurance that she won’t starve if I need to be away at the last minute for something like a client shoot or surgery or whatever. It’s nice to have that security blanket. I’m extra grateful that it doesn’t take up a ton of room in my freezer because of how flat I can freeze them. Not almost flat, but legit actually flat—thanks to my nifty little device from MAMMaway.”

Stephanie

“I just had baby number 2 8 weeks ago and have started building my freezer stash for when I return to work. I am amazed at how flat the bags freeze making it a breeze to store all my bags so flat!!! This product is awesome for breastfeeding moms. I wish I had found this product with my last baby.”

“We moved to a new place and now have a smaller freezer and it was really hard to lay the milk bags flat to freeze them. I found this little ‘gadget’ that you lay the bags in and it freezes them soooo flat… I love how flat the bags are so I can stack them easily!”
