Whenever we do tummy time, he lays there at first trying to shove his fist in his mouth or mouth the blanket. Then he sorta lifts up a few times, finally face planting and screaming until we pick him up, drooling and snotty. He's 8 weeks. He's holding his head up better than he used to while being held upright by us, but he still bobbles. But he still only lasts a couple minutes at the most on his tummy!

Who else? Is this going to stunt his muscular development??
