Boori Matilda cradle for DDs 1and 2 and it was really good - could wheel it around to wherever suited me during the day, great for next to the bed at night. They were both in it for about 4 months.

DD3 has a hushamok hammock and it is sooooooooooooooooo good. Can give it a gentle kick or shove and it moves gently for ages. I also find that depending on her mood, Miss A may prefer swaying, swinging or jiggling
