I've got a week old baby who WILL JUST NOT settle in her crib. Last night it took until 4:30am for her to settle, she's still asleep now. The night before it took until 6! AAAAAAAAAARGH! I've heard that the Amby Natures Nest is very good for comforting babies. Can I have some opinions please? It's a big investment, but maybe a small one if it means we can get some NEEDED sleep!!
