Jenny - I don't think it's bulky at all! I know some people have had some trouble with gaping round the legs, but apparently even quite big babies could do with it poppered on to the middle setting on the rise. Jamie is a big 16 months and he has it unpoppered, and I think it's fab. I got a sample to try from Octo and then bought two more. I never use it with both the boosters that you get, I just use it with the fleece one, and I find it lasts 3-4 hours which is more than any other AIO I've ever tried, except the easyfit which also lasts well. It's got leg gussets, too, so holds poo nicely. the colours are fab, mainly, I've got yellow and aqua, but I don't like the colour of the 'fresh green' one I bought - it's more like sludge green, but I've sort of got used to it now!
notcitrus - am selling my AIO Tots Easyfit...
