2 year old with disability and new baby

Cosheua

So long story short my son was born with brain damage due to a long labor and lack of oxygen. He's now two years old and is unable to walk, eat, suit up, or speak. My fiance and I just had our second child a little girl; and she's well advanced. Shes was born premature and is now three months and already so curious of her big brother. Every morning I make sure that I have them see eachother first thing when they wake up so that my son will begin to recognize her and eventually begin to kno her. Sometimes it's hard to juggle the attention between the two becauce they both need a lot of care. It can be stressful for me and they're father to explain to others why we can't do certain things like we use to or even leave our house. But my question is if anyone is going through anything similar and how do they handle everyday life?
