When my daughter was 6 months old, I had this mother over with her elder son who was 3 years older than my daughter and her daughter in which they were only 6 months apart in age. Immediately upon meeting her for a playgroup she asked about sleep and I explained our arrangements. She immediately started to tell me that my daughter was going to have sleep problems as an adult and would never know how to put herself to sleep.
I had another friend fervently try and push the "Ferberizer" on me saying that it would fix everything. And then my uncle said if they sleep with you you'll never get them out of the bed; they co-slept with my cousin (their daughter) until she was about 6 years old.
The thing about the above is that I never complained about wanting to change anything. they would ask, I would respond in honesty and then given these solutions to the sleep. That was the most frustrating part.
Now the friend who was trying to push Ferber on me for 2 years has a her little girl that cannot go to sleep until she messes with herself because it's the only thing that will relax her enough. I KNOW there is no sexual misconduct going on at the house and the pedatrician told my friend the same thing on why she does it. Not to brag but my daughter has a peaceful night's sleep and looks forward to bedtime snuggles :-)
I'd love to hear your sleep stories/journey's.
