What exactly are you doing in terms of a "schedule" for feeding? Generally speaking, in early days, a baby gets hungry, it tells you its hungry, you feed it. That's about the be all and end all. Trying to get the child into a regular routine like a toddler is just a waste of energy. Also
"not feeding him fast enough to make him happy" .. I'm a little unclear on what you actually mean here. What are you actually doing? It may just be the way you write them and describe them, but some of the things you mention sound like bad practice for child-rearing. Are you really so sure that he has been force fed, or is this just wind causing him to bring up milk before he has had chance to digest?
And seriously.. if one child is causing you this much trouble, you need to reconsider the idea of having a house full of Autists. Unless or until you have got the technicalities of parenting dead on, having more children should be the furthest thing from your mind, as all you will be doing is creating a greater stress for yourself, and reducing the quality of life of both this child and any subsequent children.
