It will all stop eventually, dont worry!! Sam settled after a week. We had a dog playpen for ours and they slept in that. Charlie took months to settle, he used to wake in the middle of the night and scrape and cry but we just ignored it, we knew he was safe. I would say he was crying to get to Sam because Sam was allowed to sleep in the big boy bed when Charlie arrived and Sam was only 4 months. Sam was house trained by then, he just stopped when he was moved out of the playpen. You just have to keep it up and dont go down to him. Its worth it in the end. Our two sleep downstairs and cuddle up on the couch together or their bed they sleep for the night. No trouble anymore!!!! Well they might be in for a shock in a few weeks when baby arrives and starts to wake them with their crying!!
