I have three children and with my second I was given a sleep sheep. I have never looked back. It is the single best product I have had for any of my children, all three relax to the sleep sheep sounds and it has meant a good nights sleep for the whole family, we used it from birth with baby number two and three and still three years on and it is used every night. It has been an excellent help when traveling and even helps during periods of toddler anxiety. When my daughter starts to tantrum she sits on her bed and listens to sleep sheep on the waves sounds and it slows her down, she can start to discuss what is causing her frustration and not descend into melt down. Absolutely wonderful product.
