L.P.
I had the same problem when my daughter was that age, until a friend told me about the "Ferber" method. Though I don't agree with all of this method, I did find that it worked to let her cry for 5 min. then go in just long enough to pat her back or talk soothingly to her, let her know you are there, then leave. Go back and do the same in another 10 minutes if she is still crying, then wait 15 min, then 20 min, etc. She will probably stop crying after 15 min. I only had to do this for 2 nights until my daughter changed the behavior. Give it a week. But, let me tell you, those first 10 min. were the longest of my life! It was so hard not to go in, but it was for the best. ____@____.com
