Hi and welcome. My first born was just like your son, and she did not have reflux. She never wanted to snuggle, and when I held her she wanted to be facing outward like you described. When I sat down with her she wasn’t happy unless I held her in a fully upright position so she could see everything. She was very, very active. Always in full motion. I think it’s just her personality. She’s still very active (but not hyperactive). She loves to dance, run around, jump, or do anyting else physical. She talks non-stop about all the physical things she wants to do when she grows up…play baseball, basketball, dance, ski, skate…you name it. She certainly didn’t get it from me or dh!!
I don’t have an answer either, just sharing my experience. My second baby was less active, and she did have reflux. She’s still more low key and less active than her sister. My new baby is somewhere between the two; quite active but probably not as active as my firstborn. He also has reflux.
