We realize that he couldn’t meet most of the physical milestones. He couldn't flip or crawl like most other kids. For 1 year Joshua’s livers reading was not normal. For 2 years they couldn’t detect the vibration in his middle year. So we were not sure he could hear probably and he could speak in eventually. Feeding Joshua worse was up because it takes about 2-3 hours to finish a meal. So can you imagine after spending 2-3 hours to feeding a bowl of serial or a bowl of porridge.
