I pulled out my calender (I record baby events on a calender, because I don't have the time or discipline to do a proper journal). Just after his first birthday, Baby:
Tore his playpen apart and escaped to run through the house.
Walked around with his head inside a bucket, smashing into walls.
Turned a somersault.
Ran to home base on at the park and did a face plant on the plate.
Stood and stomped, stomp, stomp, stomp.
Shoved Daddy's 25-pound weights around.
Cried inconsolably all night when 3 molars came in at once.
Pulled a little girl's hair.
Learned to open and close doors if they are not properly latched.
Good luck, Don!
I read that behavior seems to ebb and flow in 6 month cycles. 2 and 1/2 is supposed to be worse than 2. Same with 3 1/2.
Is he walking yet or talking much? Often just before a little one hits a major developmental milestone you will see them getting very frustrated over almost anything. Think about how frustrating it must be as he tries to do something new and doesn't yet have the language to say "help" or the cognitive skills to understand emotions. I know that I read this in a book somewhere but I have worked with so many kids of all ages and stages over the years to believe it is true.
My child was an absolute angel at one and two. She climbed everything, which made me nutty, but was otherwise mellow. She was just lulling me into complacency so she could shock and awe me with the horror of three. It worked. I'm still a little twitchy.
