My 5 month old has generally slept through the night but now will wake between 3am and 5am and won't go back to sleep in his crib without being fed to sleep although he's not actually hungry, it's just a way to get him back to sleep. Another way he will sleep is to get into my bed which I am conscious isn't the safest thing? (No judgement to anyone who co sleeps). Just not sure which route I should take, and is co sleeping really that bad?
