If you had sleep trained your baby at 5-7 months and he was good at falling asleep independently for awhile but gradually started fussing more and more until it got to the point where he would full out cry for 20 minutes or more every night when you left him in the crib, so you got into a rocking habit, but then your baby got too heavy to continue rocking by 11-13 months, what would you do? How would you get your child to sleep for bedtime and for naps? Would you go back to CIO?
