With a third on the way, I’ve gotten to know my way around crib mattresses and this one from Newton is our absolute favorite. Both of my girls used these crib mattresses which are the absolute best because they are fully BREATHABLE – meaning, if the baby rolls over, they can still breathe through the mattress. It’s also fully washable – not just the mattress cover, but the actual mattress core can be thrown in the bathtub and thoroughly cleaned. Because of our love for the crib mattresses, I just ordered Newton’s twin mattress for transitioning the girls to big girl beds which will be happening in the next few months. Right now, you can get $50 off any mattress with the code Mary50. Also, if you’re pregnant, snag their pregnancy pillow here and use code MARYORTON for 15% off. It’s the best one out there.
