I had the HAB when he was little but now use a peanut style. Like Sarah said, great for quick use. I use it when I'm ducking into the shops or if he wants me to carry him because it just takes that weight off my arms and I can use both hands too, so very handy. I still do really like the HAB especially for little bubs as they're really snug and Oskar used to sleep in it a lot and it enabled me to cook dinner and do the washing as he wouldn't sleep on his own back then.

oh.. I have had him in the HAB only about 2 weeks ago and he was still fine with it and it held him really well... he's now 11 months old.
