The only way you're going to find out, is to try it. I do add a little bit of oil and agave nectar to mine and my hair is always very soft and shinny.
I add my gel over my leave-in and dry with a diffuser. There is a point in the drying process where my hair does feel a bit stiff, but I just keep drying it until its done, then scrunch any crunchiness out.
P.S. Congratulations on your little one coming soon.
