Hi there. My baby girl was like that when she was born. She acts like she was choking whenevr i try to feed her on an elevated position on my arms and cries. But when i lay her on bed she stops and drinks her milk with her head tilted sideward. So whenever i feed her she has to be lying flat on bed. I just put a pillow under her head for elevation. My baby also sweats alot when being held. But now that she's 15 mos. She drinks her milk on her own in an upright position. maybe its just their preference. But if you're still worried better to consult it to a paedia.
