I bought this for my daughter when she was two days old, as I couldn't get her to settle in her moses basket by herself. The sheep toy is very sweet, but I didn't actually put this in her basket - she likes looking at it, but it's a bit too big for the basket. It attaches quite securely to the bars of her cot using velcro strips.
The unit inside with the sounds was great at settling her and is small enough to use in the moses basket. Once she got used to it, we used it for daytime naps and I even put it in her pushchair when we first went out in it.
I tend to use a white noise cd more now to settle her at night, but this is still a really useful item, especially when she wakes at night and we want a timer for the sounds, rather than putting a cd on. (She still sleeps in our bedroom.) Once she moves to her cot, I will put the little unit back inside the sheep.
