My child wants to be independent but gets really messy: Advice?

I need some advice, so my 11 month old boy wants to be independent only self-feeding allowed. And forget about spoon-feeding a tantrum is thrown I am tired of every breakfast, every lunch, and dinner bathing three baths a day is so much my 5 yr old son was not this independent before 1 yr old I need advice big time, and he only wants normal food baby food is no longer good enough for him. Please any advice at all I will be grateful
