I had never heard of wonder weeks before but it fits his recent behavior 100%. It is a sudden developmental leap that typically happens around 19 weeks and can last 4-5 weeks. Check out this blog that one of the WTE momma's suggested: Bloggin About Babies.
Like I said I believe we are actually past or almost past wonder week 19. Thank goodness! It is absolutely amazing the development that Jameson has made in the last week and a half. He has way more coordination, can sit unassisted for about a minute, is rolling over, and when you ask him to say mama....he says mmmmm! I am pretty excited about that last one. There are other details of his movements and the way he looks and plays that have also changed.
So I want to take a moment and thank my WTE mommy's for being there! This first time mommy would be lost :)
