I, too, am a married 32 y/o with a 13 month old baby girl.... she has the same problems about not wanting to go to sleep... according to my pediatrician, this is a very normal phase..... al babies between 10 months and 2 years go through this at least from time to time-not sleeping through the night or not going to bed- he actually suggested that if we establish a routine (like bath, story, snack, bed) that it doesn't matter if she goes to sleep on her own or not.... sometimes we rock her, sometimes we lay down with her until she falls asleep, others we sit with her until she is ready to go to sleep on her own.... before you try the "ferber method", make sure it is not something else going on....
have you cut out an evening bottle or are you cutting out bottles in general? changes in routine can make her not want to sleep...is she hungry? she may want a small snack and some milk before bed if it has been over an hour or two since dinner.....are you gone during the day and she is not near you? she may just be lonely for you and miss you and need some extra love.... is she cutting teeth? that can be very painful and she may just need a little motrin to help ease the pain that she feels when she lies against her face.... also even ferber-fanatics do not suggest using that method with a teething child... they need comfort not more distress....have you been co-sleeping and are trying to put her in a crib now? even a couple nights of co-sleeping can throw off a baby's routine if they are expected to sleep in a crib the rest of the time, and it is hard to give up the cozy, comfort of cuddling with mommy all night...
remember, this is your child and your decision... personally i could not use the ferber method if someone paid me a million dollars.... if you choose to that is up to you.... whatever love and comfort you give to your child now will pay off...it may take more time to get her to sleep and it may be hard on you for a while, but studies show that in the longrun, babies will at some point sleep on their own and do fine.... you may just have to wait for that day to come later...hope it helps
