I need some help. I'm at a loss. My 21 month old DD2 is a terrible sleeper. Always has been. Very few good nights ever. She does better sometimes, and then long stretches of terrible. She's almost 2! I have a good routine. My 3.5 year old is an amazing sleeper. My husband and I are good sleepers who love sleep. Why does baby #2 sleep terribly? She has laryngomalacia so I don't like to let her cry it out for too long (i've tried but she will scream for an hour straight and her breathing takes a long time to recover).

Has anyone had any luck with sleep training a 2 y.o..? Did anyone's child just sometime start sleeping better? I feel like hiring a sleep couch but hate to spend the money on that.
