It wouldn't be much of a big deal if you were eating finger foods but to grab the spoon and bring it to your mouth without spilling is quite an accomplishment - to me at least.
We've worked on this extensively on many mornings. You insist on trying it yourself but wouldn't quite have the dexterity to bring the spoon to your mouth without help. I'd take your wrist and gently guide your arm in the right direction. My thought is that muscle memory would develop and eventually take over.
Eventually it did but as you can see from the video below, you've got some practice to do.
We'll keep working on it until it's perfecto!
If you wonder what you're wearing in the video, it's Halloween Day at Marissa's. Each of her kiddos is supposed to dress up in their costume. You, of course, are your favorite cartoon character ... Minnie Mouse!
