I bought the Ikea one and used that from around 7 mths I think, and before that I just fed her in her bouncer. She wasn't as wriggly or messy as she was later on so that worked fine. The Ikea chair is great - soooo easy to clean, I hate how food gets stuck in all the little nooks and crannies of chairs with lots of padding although they look nice. We used the blow up insert until about a week ago wiht our Ikea one. I am also getting on of those plasticy travel chairs that you use on any chair from a friend, as they are easy to take everywhere. Having said that, with the Ikea one, the legs pull off really easily if you want to chuck it inthe boot to take somewhere.
