I'm going to start a review section of all the baby gear that has worked - and some that haven't.
To kick off - I present to you, the Totseat. £22 if you are buying in the UK. Their website gives details of international suppliers.
It's a genius lightweight, portable high chair. Especially good for pokey restaurants and cafes and a tactful way of avoiding grotty, dirty or just plain broken highchairs that some places are so thoughtful to provide.
I keep this in the bottom of the pram. It goes everywhere with me and has been borrowed by a number of friends for holidays and emergencies. Despite appearances, it doesn't turn all babies into beer-crazed fiends.
