Child care Kenya and Ghana volunteer

Hey, how are you? I'm Franky, I'm 21, this is going to be my first trip to Africa and all I want is to make others happy specially kids, there are many kids who need help, support and love so I'm going to volunteer to kenya and Ghana for more than a month, it's going to be expensive for me and I want to bring toys and materials so for the kids inAfrica, I already bought a lot of things for them but I still want to do more, maybe even buy food in Africa and just use your money to help people over there and some money to help my self with the flights as well, like a say expensive but worth it, I'm so excited so please, I will make an impact in others lives if you help me, I will be so grateful, thanks :)
