My 6 month old is having a very hard time adjusting to eating baby food. He cries and screams and flings his body away trying to avoid the spoon. I tried singing to him and making it more fun and he likes that, but once the spoon comes into the picture, it is not fun anymore. I put the food in his mouth anyway because I think he is just getting used to it, half he spits out and the other half gets swallowed. He is a big boy and loves food, he just isn't a fan of this new arrangement. He has some constipation issues and his pediatrician says no rice cereal, bananas or applesauce which may taste better than the options I currently have for him. What do you recommend?
