Pre sleep training, I didn't think it would work. I thought it would be negative for the kids. I thought it would be a waste of money.
Pre sleep training it was taking 45-90mins to put my boy to sleep. Waking up in the middle of the night almost every night, and then again at 5am. We were exhausted.
Within two days of the sleep training he was asleep within 10 mins and by the end of the week, within minutes. No waking up in the middle of the night at sleeping to 7-8am.
I can highly recommend them.
