Little boy needs surgery

My 2 year old son was born with a bilateral cleft lip and palate. There's a gap somewhere near the middle of his mouth where his lips should be joined. When he was an infant, it was hard to feed him because the milk could get in his nose if he was not fed in a certain way.

Other kids stare at him and/or are afraid of him, because he looks different. He can't speak much yet either. But he is playful and a cheery little kid. He gets confused when others won't play with him, but he keeps on trying.

He went through three surgeries already, the first one was from a non-profit organization for people with cleft deformities, it was not successful. A few months later I decided to go ahead with another surgery because people especially kids are afraid of him and it breaks my heart to see he's being laughed at. It was a successful one, his lips were closed. After 6 months, a free surgical mission was offered in one of the hospitals here, he had his palate operated but since the hole in his palate was very big, his soft palate was left opened and still needed to be closed.

I would very much like for my little boy to live a normal life. However, being a single mom, it's hard to save up enough money to get his surgery done. I'd like for him to get surgery as soon as possible in order to have the plate closed, so he can talk properly.
