Head hitting is pretty disturbing...but I'd have to say normal. Sorry. At 1 1/2yo they know alot. They know what they want, why they want it and when. But they just can't tell you.
It's also pretty normal to want something right this second. They really don't understand waiting yet. He thought of lunch right now, what's the problem with you having it ready right now? That's probably what he's thinking. He doesn't realize that you have to finish what you're doing and prepare it.
IME, the best way to deal with this is to just tell them "I know you're angry/frustrated and that you really want to play outside right now. I wish I could let you, but I really need to finish cooking (or whatever) first" and be ready to offer lots of hugs. My baby loves to play outside, but I can't always let him at a moment's notice. And when I can't he gets upset. Usually after a good cry, talk and cuddle I stick him on my back and he'll wait a bit more happily.
