Use it in the morning if you do not think it's working!
This is a great product and is much less messy than other options. I have three kids, 9, 3, and 18 months and we have used for about a year now. At first it seemed to make my children sleep worse but that was because it helped them get to that deep rem sleep and that caused more dreaming. So we stopped using it at bedtime and started using in the morning so they still get the benefits without the dreaming issues.
