She can already do 'this' and she won't stop unless you stop singing (or even after that)... At 4 months, she already does the close-open stint. I do not know if this is because I have been trying to teach her the baby sign for milk or because she was taught by her Ninong Laurence to do so.

I didn't notice that she can actually do it until I was showing her the milk sign again. She responded as if she knew what I was telling and 'acting'. If I remember it right, i started doing and teaching the milk sign to her when she was 2 months old. I was just trying to familiarize her with the movement so that she can do it when she's a little older. Then I stopped for sometime because I forgot about the signing. Now, I am into signing again.

So back to 'close-open'... This was even intensified every time her ninong would play with her. During her last check-up, her pedia saw this and she said that she is advance on this level. She said that close-open is usually made during the 8th month of the baby. I just hope that she'll be more keen on her rolling too, even if we need to install exit signs for her to follow.
