I would say disagree. I think babies are probably fine with nutrients etc but for me it's more that they need to learn to eat.
My 9 nearly 10 month old still isn't that interested in food, will only tolerate mush, gags quite a lot as struggles to move food around her mouth. But it's not like she'll get to 1 and suddenly start eating so I feel this time is important for her to be getting her practice in. Whereas if it is just all just thrown on the floor and mushed in her hair, she is going to struggle, especially when she's at nursery all day soon without my boobs for back up.
So while we keep it 'fun', I think that word is a bit misleading as I think it is quite important.
