Well, my first threw her first wall-eyed fit the day after her first birthday. I think my second child blessed us with this experience somewhere in his 11th month. It's just him flexing his toddler will power muscles.
One thing that might help is to start getting in the habit of letting him know what's going on. All this time you've been able to go from one thing to the next and just pick him up and take him along, or move him along without telling him about it. He doesn't get a choice in the matter, of course, but some preparation might help him transition better. So, in the morning, instead of just picking him up, first let him know it's morning, time to get up, and say what you'll do next. Maybe even let him play for one minute before you come back to get him, and continue letting him know what comes next in your routine. Remember that your TELLING him what's next, not asking.
He's just testing to see how much control he can have over you and the routine. Don't give it to him. The fits just get worse if you do!
