Nakita has been stcking her tongue out for months (yes she is only three weeks old), in one US in my OB's office she was licking her umbilical cord, we have a 3d photo @ 29 weeks with her eyes open a stcking out her tongue, and now that she is here she does it a lot - no wonder we saw it on scans!! Not necessarily at food time either! You can click on my blog link in my sig, there are a lot of photos with that tongue poking out!!
