For example: my 13 week old daughter, for the last couple weeks has been starring at her hands and starting to show interest in objects. Well the other day we were going for a drive and she gets bored so I gave her her pacifier, she likes to chew on it and spit it out. Usually I put it back in her mouth, this time I was eating so I didn’t do it immediately and she opened her mouth, took her hand, grasped the pacifier and maneuvered it back in her mouth. I thought it was just an random thing she managed to accidentally do but then she spit out again and did it again! I watched her do it like 20 times! I couldn’t believe what I was seeing!
