AARRRGGHHHHH!!! Admittedly, I've not had ANY experience with "the family bed" or "co-sleeping" that seems to be the fad these days. . . with the exception of reading a book before bed, or watching a movie, or reading the comics in bed on Sunday morning our children and grandchildren did not and DO not sleep in our bed. And, suddenly thinking that children are better off by sleeping in mom and dad's bed is a load of garbage.
Families slept together in pioneer times because they had to, not for the well-being of their children.
Whenever I hear about this latest fad of co-sleeping, etc., I remember my sister-in-law, who waiting so long for her children and cherished them so dearly (and still does) but who made the mistake of believing that her daughter needed her to help her get to sleep (even though her older brother never had that problem). She began staying with her every night, stroking her back until Lauren decided Mom could leave or until Lauren was asleep. Fast forward ten years ---- Mom was STILL laying in bed with Lauren, stroking her back until she fell asleep and Lauren was TWELVE YEARS OLD!!!
I just have one question for believers of the "family bed". What happens to their personal life? Do they just give it up until their children decide to sleep in their own beds? Do they continue with their private life while their children are "sleeping" beside them???
Okay, so YOU have created this situation with your child by giving her the idea that she HAS to have one of you there to sleep. Fair? No, not to anyone, especially her. But now it's up to YOU, the adult, to make it right. Trust me, when she's grown up, she'll never remember the tough week she had learning to sleep in her own bed by herself. This is what she needs.
Honestly, had anyone managed to track psychiatric problems or lives of crime back to "I was forced to sleep in my own bed"?? I don't think so.
It's not an ideal situation, but your 2-year old has done nothing but take her cues from you. And you have conditioned her to think that she can NOT sleep by herself. Now it's time for you to show her that she CAN.
