Sleeping through the Night

So Tony and I have tried everything to get Caroline to sleep through the night...and I mean EVERYTHING! She has cried it out many times, she has a bedtime routine, she has had cereal in her bottle, cereal off of a spoon, stayed up late, gone to bed early, we have done every song and dance to make this happen. So about a month ago I just gave up and got up once a night to feed herand figured that's just the way it was going ot be for a while. Well, the last night we were at the beach, she slept through the night in her pack and play. We get home and she does it again last night...12 hours! Wow...so hopefully this will continue! I guess it just goes to show you that when they are ready, they will sleep through the night....no matter what the parents do! ha!
