When you look closely however, you can see his head is not "normal".
The following picture illustrates the difference in head shape between a normal head and a person with Microcephaly:
The following photo shows Joshua with another baby of the same age (born the day before him). You can see the difference in their heads quite clearly, as per the previous illustration.
Typically, a baby has a big boofy head. When you look at Joshua's head from the top and the back, it doesn't look nice and round like a normal head, it looks somewhat rectangular.
Where the difference is most obvious however, is when you look at the size of his forehead area. This really hasn't grown since he was born and is extremely noticeable when you look at it from the right angle, as it gives him a 'conehead" like appearance. This is shown in the photo below:
When looking at him from behind on a slightly side on angle, you can also see that his head looks small on his face.
Joshua's head is like this because the damage to his brain has prevented it from growing normally. It will likely become more obvious to people as he grows bigger. Like HIE, Microcephaly is associated with poor outcomes, however it is also possible to have microcephaly and still be highly functional so this is just another one of those things that we have to wait and see on. His doctor has told us that she would expect him to be a lot worse off given his head size, so in some ways, that is a positive sign.
In the mean time though, it is just super hard for me to find hats that fit him :)
