Oh I get so mad for parents when they say that they've expressed concern and have been fobbed off. That's not fair... not to mention not ethical. You're his mother, your instincts and observations are telling you something's up... your GP should give you the credit and the respect to follow through with more discussion and investigation.

I don't know anything about club foot specifically or its comorbidity (other disorders that it commonly presents with). It's hard to tell just from the info you've given what, if anything might be going on... The tendency to bang rather than play with objects does stand out to me, but alone is not enough, and he's still so little...

You queried autism... Here's some areas (questions taken from an autism acreening tool) you can think about and perhaps make notes on for your specialist appointment which will help them rule ASD in or out:
Emotion and Eye Gaze
Do you know when your child is happy and when your child is upset?
When your child plays with toys, does he/she look at you to see if you are watching?
Does your child smile or laugh while looking at you?
When you look at and point to a toy across the room, does your child look at it?

Communication
Does your child let you know that he/she needs help or wants an object out of reach?
When you are not paying attention to your child, does he/she try to get your attention?
Does your child do things to get you to laugh?
Does your child try to get you to notice interesting objects — just to get you to look at the objects, not to get you to do anything with them?

Gestures
Does your child pick up objects and give them to you?
Does your child show objects to you without giving you the object?
Does your child wave to greet people?
Does your child point to objects?
Does your child nod his/her head to indicate yes?

Sounds
Does your child use sounds or words to get attention or help?
Does your child string sounds together, such as uh oh, mama, gaga, bye-bye, bada?
About how many of the following consonant sounds does your child use? Ma, na, ba, da, ga, wa, la, ya, sa, sha?

Words
About how many words does your child use meaningfully that you recognize (such as baba for bottle; gaggie for doggie)?
Does your child put two words together (for example, more cookie, bye-bye Daddy)?

Understanding
When you call your child’s name, does he/she respond by looking or coming toward you?
About how many different words or phrases does your child understand without gestures? For example, if you say, “Where’s your tummy,” “where’s Daddy,” “Give me the ball” or “Come here,” without showing or pointing, will your child respond appropriately?

Object Use
Does your child show interest in playing with a variety of objects?
About how many of the following objects does your child use appropriately: cup, bottle, bowl, spoon, comb or brush, toothbrush, washcloth, boy, toy vehicle, toy telephone?
About how many blocks (or rings) does your child stack?
Does your child pretend to play with toys (for example, feed a stuffed animal, put a doll to sleep, put an animal figure in a vehicle?
