They also make on the go beds for baby when you go to grandma's. I'm not sure the brand I think it may be summer infant actually, but I like it well enough. Co-sleeping is NOT for me, co-sleeper or not, I wake every time the baby inhales, so I didn't get much use from mine. it fit well in my king bed, has a little light which was helpful at 2am, because it has sides you have to pick baby up rather than just roll baby back to their space like you would do with the arm's reach sleepers. i found it best to not share a blanket with DH, just in case it came up over the co-sleeper. I would have been happy to keep using it and to use it with the new baby as well if I would get any sleep.
