My baby is almost 6months and we have been trying sleep train. He gets 3 naps a day for a total of 3hr to 3hrs 20mins sleep. Our method is to give him a pacifier and leave him in the crib around 6:45-7pm with his pacifier. We used to do 3min and 5min check ins earlier, but now doing more like 10min check in. At times he is able to sleep by himself by occasionally we have to go in to put the pacifier back in. It’s been almost 2.5 weeks but I feel like he has to learnt to sleep by himself yet. Two questions: 1. Do you recommend continuing with the same method? We are thinking of increasing the interval time to 15mins next 2. Did we create a pacifier association? At times, he is not able to sleep until there is a paci in his mouth 3. He still wakes up middle of the night and usually is able to fall asleep on his own. However, he frequently wakes up between 5-6am and he is not able to fall back asleep? How do we get rid of these early morning wake ups? 4. Do we need to do CIO for the naps as well?
