Around the time Asher was eight months old he had to have surgery to repair a hydrocele. This issue can be hard to resolve on its own in children who have shunts due to the area where the shunt drains.
When Asher was just over a year old we took him to have allergy testing and discovered that he's severely allergic to milk and egg. This was prompted by a couple of adverse reactions to milk products. We were sent home with a prescription for epi-pens and told to come back for testing when he's three. His allergy issues have only added to the difficulty of getting him to gain weight.
