Monster started reaching for his toys, batting at them, and yanking on them just over 3 months ago. Since then he has been working hard to develop his fine motor skills, and dexterity. In the last two week, he has gotten ridiculously good at grabbing and stealing things!
I've nicknamed him Klepto-Baby, because each and everything I hold in my hands he reaches over and steals (ultimately to try and shove into his mouth). Actually, statement correction: I don't even have to be holding it, it just has to be in reaching distance. Monster enjoys very much "helping" mommy use her phone, or eat her food.
Which, in fact is where I think it all stemmed from. We started feeding Monster solids earlier then most. He first tired rice cereal at 3 and a half months old, and since then has a large list of fruit and veggies he enjoys on a daily basis. My theory is that since I feed him with a spoon, he thinks everything from my hands should go into his mouth.
That theory is easily dissolved with the shear fact that most babies pick things up, and stick them into their mouths.
