i just gave birth to my second with an umbilical hernia. it was not very problematic. it did get sore in the surrounding areas and i found it very helpful to pop the hernia back in. i did this by relaxing my belly -- usually laying down -- and just gently applying pressure and moving the bulge until i felt the pressure release as the hernia moved into place. it made a huge difference to do this as soon as i felt extra pressure in that area. in fact, my midwives got a kick when i paused during labor to tend to this task. i didnt want any surprises at that point, you know. also, i made it a point to exercise. figured it would help strengthen my core, and could only help. walked 3x week for 1 hour at a quick pace, being very conscious to hold my core muscles strong. good luck. i know there is not much info out there.
