My mum has looked after Zander every Friday from when he was around 3-4 months old so she has had to have a decent one for him. She got a Jeep one, basically cos she liked the look of it LOL!! It has music, a light & a vibrating function but none of them have ever been used! The thing that was great with it is an extra matress, it folds up like an N so it is very portable as well. It makes the cot way more comfy then the other thin mattress it came with. There's also a bassinet attachment to the top, half is bassinet & the other half is a change table.
