"We are so grateful for Marissa’s guidance along our journey as new parents. Our son had feeding challenges and serious colic in the beginning and Marissa took our whole picture into consideration when giving us advice on sleeping. Of all of the baby experts we worked with, Marissa was the most consistently right about everything!"

Marissa’s Sleep Story

After my first son was born, I devoted many hours to reading and researching about baby sleep. As a result, he was a decent sleeper early on. But, as is the case, so many families come to realize, the “one size fits all” approach didn’t “fit” for my second son.

Exhausted from trialing (and failing) different sleep methods, and keeping up with my eldest, who was now a toddler, I turned to Sleep Wise. My consultant took an in-depth look at my son’s whole day. She identified potential causes of his sleep disruptions, and offered informed recommendations to improve his sleep. As a result, we saw improvements in his sleep from the very first night!

I was so impressed with a sleep training solution that was varied and nimble enough to work from child to child! I decided to use my background and passion for babies, children, and families to join the Sleep Wise team. Sleep has a huge impact on a growing child, and the rest of the family. I am grateful to be a part of this life-changing solution for so many!
