What is going on?!? Lol. My twins are only 3 weeks old and my son already holds his bottle (from the bottom) my daughter already rolls over, literally, from tummy to side to all the way on her back and she slides or scoots whatever you wanna call it so I have to be very careful where I put her. My son laughed the other day, my daughter can lift her head completely up and look at me when she's on my chest. My family jokes and says they're moving out the way for another. NOT! Seriously though, why are they moving so fast? or am I tripping and this is normal?
