This is what happens when you feed a baby lots of food and keep awake and playing long past his bedtime.
You turn your back for just a min. and he goes all quiet. He was so tired that when I picked him out of there he barley moved.
This is what happens when you turn your back on the older one and he is feeling adventurous.
He will climb into the crib of your younger one and wake him to play. Then when you get the camera out to take some pictures he will shove his younger brother out of the way so that he can have some solo shots.
This is what happens when a baby gets excited about crawling.
He will get up on his hands and knees then sometimes when he tries to move froward he uses so much energy that he just pops up on his tippy-toes. Other times he just can not get the rhythm down and ends up moving backwards.
