We bought the Newton mattress for my son in 2018 and are now using it for my 6 month old daughter. We were living in Tucson when my son used it and loved it. However, we are now living in Seattle and I feel like my daughter constantly wakes up cold even with us setting the heater to 72 degrees. She goes to bed in a fleece footed PJs just like my son did. Has anyone else had this problem? Did switching to another mattress help? We would probably still hold onto this one for the warmer months, but I’m really tempted to try out a more traditional mattress.
