I've bought a lot of mobiles. It started with electro-Mobile had the very many functions. Then we continued with mobiles having only turned, but that was all not so right for my three young men (5years / 2 1 / 2years and 4Monate). When I did the experiment with this rather simple mobile, everything went really well from the start. It's nice collar and my little son (4 months) like it just great. I can only recommend this Dragon Mobile! Super cute and super cheap!
