I dropped him off in the morning, and picked him up a little over 24 hours later. I told him "You're going to be sleeping at this house tonight, and I'll come get you tomorrow. " After I dropped Andy off, I went back home and my husband and I, and the girls got in the car to drive to a waterpark hotel. We had fun, but the 18-month old was exhausting. My older daughter had a great time. We ate at a cafeteria buffet with no wait time for our meal, so that worked out great for us. The baby slept just fine in her temporary crib in the hotel room, and even took a nap in there because the room could be darkened.
We left the hotel the next day, I took everyone home, and immediately left to pick up Andy. He seemed happy when I picked him up. He was watching TV with his earmuffs on at one pickup, and the last one he was sitting by the window looking outside when I picked him up. He was happy in the car all the way home, and most of the day once we got back.
The respite home has been a great resource for us so far. I do still want to attempt a couple nights away with Andy, but they are usually stressful. We will be taking him up North and to our camper for the day and we will see how that goes.
