I mentioned earlier that it is fun to take similar pictures of the years so you can see growth with a comparison. Here is one I took a few days ago compared to the one I took when he was a baby. In both we have the Kermit the Frog as a reference.
It can make for a fun scrap book page as your chronicle their history with the one object. you can do it subtley or very obviously, its your choice!
Have fun! Happy Holidays!
