*Your BabyThis week starts a period of rapid cellular development for your baby-to-be, who looks like a mini tadpole, with a tiny head and tail. His or her eyes, ears and mouth have begun to form (though they're a little more Discovery Channel "creatures of the sea" documentary than Gerber Baby at this point).Other exciting milestones include:Your baby's heart is now beating to a regular beat, although it's still too faint to hear.His or her arm buds are just beginning to, well, bud. They look like teensy swollen bumps at this point. In a few days, they'll resemble itsy-bitsy flippers.Your baby has grown to ⅛ inch long—about the size of one of the chocolate sprinkles on your last cupcake (and your last ice cream cone, and your last sundae and your last giant cookie ... maybe there is something to those rumors about pregnancy cravings!).*
