My daughter, 19 mo. had her soft palate repaired. She stayed
for 4 days in the hospital since she refused to eat and drink.
She wore her restraints for 2 long weeks. She was very quiet
afterwards and still is. She has always been a quiet kid though.
Anyways she used to "talk" more but now she doesn't say
much. It has only been 5 weeks since but she is still recovering.
Don't expect your child to bounce back immediately. Good luck.
