We have an Amby one. There are some pics on the website if you click on Oskar's name. One in the birth to 12 weeks folder and then one in the 12 weeks to 6 months. He's almost 14 weeks and still in it and loves it. He's partially wrapped...by this I mean from under his arms as he doesn't like his arms wrapped. Then I actually tuck him in with a cotton blanket so his arms are held down but he can get them out. The blanket I tuck under the mattress so it's firm across him. The pics don't show this though cos I only put it on him when I go to bed.
