I saw that picture the other day too! I had to look twice because your baby looks like my baby! 
 
 
Jimmy is almost 5 months too (on the 10th) but he hasn't really started changing anywhere but his head. I'm anxious as all heck to see what it looks like. 
Yeah, I do hear they change a few times or maybe not changing but prgressing? 
I really cannot wait for the finished result but I want him to stay like a puppy
