My 5 nearly 6 month old has just started waking up all night when I give him dummy he falls straight back to sleep. He’s not waking cause he wants a bottle, I read they fully wake after each sleep cycle and they way they go to sleep they need that method. He has a dummy when I put him down he crys lots and I keep putting the dummy in and he finally falls asleep, I don’t like the cry it out till they sleep method. What can I do about his waking all night? He’s not cold/hot think it’s just the end of a sleep cycle?
