re: OT moms, why the reduction in titty feeding?

I will say that my daughter is developing quickly in a lot of areas my son didn't. She already attempts to mimic sounds like hi and hey and ooh. She returns smiles and can follow some repetitious behavior like my wife kisses her on the nose and and goes oooohhh and our daughter responds by throwing her head back and doing ooh. Once my wife went in to do it and stopped and my daughter started to go back and made the noise but caught herself cause she wasn't kissed. Amazing stuff really...
