DD is six months old and only goes to sleep on the boob. She refuses a bottle and gets very upset when tired if she isn't with mummy. None of these things are a dreadful problem except........ I go back to work in three months which will involve the odd night away when DH will be in charge of baby and 4 year old son. I'm therefore forced into the position of having to so something about this rather than wait it out like I did with DS (who went to sleep on boob or bottle until he grew out of it). HV and others recommending controlled crying. Any experiences or advice to help me decide?? Xx
