Hello Doctor I have some questions I'd like to discuss. My babies are now 11 months old, both of them have a genetic condition (Dwarfism), which affects certain aspects of their development. One of my babies crawls on their stomach, while the other doesn't. They don't sleep much during the day, usually only 1-2 hours. They typically sleep from 10 PM to 8 AM, and their soft spot on the head has not yet closed. I'm curious about how long it takes for the soft spot to close, the typical amount of sleep for babies at this age, and when they might start walking.
