Our baby has like this since he received at the age of 5.5 months and we will not bear too bad, thanks to songs that are quite cute, very varied and not too strong. (It was anyway begins to wish for "hello little squirrel" in the morning, but for now I have not want to throw it by the window ...) The small mistreats with kicks from 2 months and for the time the product resists to attacks. Only criticism is the affixation is not great, it does not take very well, we could surely tinker a solution easily.
