Where I live, there are these HUGE Motherhood/mummy exhibitions or fairs. There are always plenty of options for baby weaning products and equipment for sale to help mums prepare foods and purees for their babies. I think they have pretty awesome steamer-blender combinations that combine the tools that you need into 1 handy gadget!
Not that all of this stuff isn't cool and nice to have, but with all the extra things you're buying for the baby as it is, I'd rather keep all the additional appliances to the bare minimum!
I love the idea of silicon ice cube trays though! Definitely beats the plastic variety that many people are used to having and it's probably going to be a heckuva lot easier to get those cubes out for feeding too!
