I have a 5 day old baby boy. When he was less than 24 hours old he lifted his head and held it up for like 3 seconds. Today he rolled from his back to his side on a perfectly flat surface... UMMM what am I missing? I thought these were things he was supposed to learn later in life... Why is it happening already? He is my fourth and final child. I just want him to stay a baby as long as possible so why on earth is everything happening so fast?
