All of my children loved bouncing from the door frame in a door bouncer; it was a great way to kill some time and cheer them up when they were feeling less than happy or fractious and bored with all other activites - bouncing ALWAYS produced instant giggles and smiles...for me too, not just them.
This Lindam door bouncers is suitable for babies who can hold their head up, unaided, from three to 15 months and the maximum weight limit is approximately 12 kilos. It attaches to interior door frames using a spring-loaded clamp and are fully supportive. They are adjustable and the little saddle/seat/hammocky type thing (or whatever you want to call it) is washable.
The door bouncers I bought were some of the best baby 'stuff' investments I made, and produced the most fun - if you've got £11.10 floating around, or someone has asked if they can buy your little one something then I'd really consider going for a door bouncer of some description, they really are great.
