My daughter has been playing with this since she was about 6 weeks old (she's now 5 months) and still hasn't got bored of it.
We clipped it onto the side of her cot and she loves playing with it when she wakes up in the morning. The only down side is that we end up waking up to a loud crinkling noise every morning where she's squeezing it!
I thought that I was taking a chance with this Lamaze toy because there were no user reviews but it has been brilliant and well worth the money.
I have also stuck it in the washing machine when its gotten in the firing line when she's been sick (even though it says wipe with a damp cloth) and it comes out perfectly every time.
A great, fun, bright, durable and practical toy that should keep the little ones (and sometimes the big ones too) amused for hours!
