Ds3 is 8.5 months and loves his dummy. However I'm up at least three times in the night to pop it back in as he wakes when it drops out. He only has it at night. I've kept using it as ds2 is a very light sleeper and will probably wake up screaming if he hears ds3 going cold turkey. What should I do? How do i wean him off it or shall i just keep the peace and carry on as we are?
