Just the 2 of Us

So for the first time in 5 years, we went away. The last time the 2 of us were away without any children who were born, was back in 2006. We went to SPI (South Padre Island) to celebrate our anniversary. Luke however went along for the ride, literally. We enjoyed a day and night of walking along the surf, watching dolphins, going to a seafood restaurant (and not ordering seafood) and relaxing. Since Luke was born, we have not been away together without children. We have been away separately, but not together. So we got a babysitter for a night, and away we went to the faraway land of Pittsburgh, PA. We went shopping, and out to eat, and relaxed at the hotel. We even slept into 830!!! It was great. We also had a little one along for the ride this time as well, but they behaved and didn't cause any problems. So we have agreed we will have to do it again sooner than 5 year from now. The boys did great and didn't cause any problems. This is great, but why when the babysitter stays the night, do they sleep all the way through, and when Mom and Dad are home, do they wake up and want to play for 2 hrs?????
