I am at the end of my resources with regard to A's sleep. He is 5.5 months and for the last 6 weeks has been waking up every 2 hours or less at night. It's exhausting all of us! So, I'm going to call for a personalized sleep consult with Isis (http://www.isisparenting.com/product/ISSVV_SSC)
Have you ever had a sleep consult? Did it help?
