i would see the paed to put your own mind at rest - if the GP seemed disinterested, it's definitely worth getting her checked properly

FWIW - my mum has developed reynauds in adulthood - she wears gloves all the time when the temperature drops cos if she doesn't her hands go white and she loses sensation in them. no idea how to help with a bubba but wanted to let you know mum's experience and to send you big hugs - it's not easy dealing with anything that hurts our kidlets!
