Hi mythreeboys...I just wanted to tell you that the stress of getting only 3 hours sleep a night AND having a colicky baby is huge. Stress can be emotional AND physical too. What I mean is that I learned that even if you don't feel stressed, your body can be stressed...just not your emotions...if that makes sense. So 3 hours of sleep a night can physically stress your body while the colicky baby can emotionally sress you out. SO, telogen effluvium is a real possibility. Are you getting a lot of self care now? Relaxing, guided imagery, hot baths, etc? We moms forget to tend to ourselves sometimes. As far as the mattress goes, I can only say that it won't hurt to get rid of it and go back to a regular mattress and can only help. I once bought expensive down pillows because they were SOO comfy and I got little bumps (rashes) on my back and chest....was so weird. lasted for months. I asked myself what I did differently and the answer was the pillows. I got rid of them and never had the problem again. SO, I can't say it WAS the memory foam mattress and I don't know anything about them, but if this was one of the few changes you remember back then and your hair loss persists, it cannot hurt anything to try getting rid of it. But remember it takes 3 to 6 months before hair grows again after trigger is removed. I am praying for a beautiful outcome for you...for us all! Was a great group of women on this board! Big hugs to you.
