Can anyone recommend a good night time cot lullaby/light sort of toy?

I bought a Tomy Dreamshow thingy. It plays lullabys and has a little light projestion on it so the ceiling becomes a canvas for it. My daughter wouldnt go down on her own for the first three months but after that she satrted to suck her hand and as i was rocking her to sleep in my arms, when i notcied her doing this i knew she was tired and so i just put her in her cot and after afew miniutes sucking she was fast asleep. I dont think they have the ability to go down properly untill they are that bit older. Anyway there you go. Also you could try a lillaby Cd?
