Okay so my son's pediatrician never told me his soy formula would mess with his thyroid meds and…

maybe you should wait longer before feeding him?

giving it after his food results in projectile puking so I have waited up to a hole feeding period so this has not always happened. I know my child lol

I would call his doctor on Monday.

his dr will say just to put him on the blue similac cuz most babies don't have a .milk or lactose allergy and he won't test for it

Did the doctor put him on soy formula or did you choose it for him? I know when doctors put babies on soy formula it's because they can't digest lactose. my daughter and my niece and nephew all have a lactose sensitivity. my daughter and my nephew are on the sensitive similac and my niece is on the soy Enfamil.

you can always try the blue similac and see how it works! it takes a few days to start seeing how it really takes with your baby but if it keeps him from throwing up his food, I'd say it's worth a shot.

I did because the dr would not test him for a milk allergy until he's three and both sides of our family have had milk allergies as babies

@katarama,

@thatmomlyfe16, Is the soy formula Similac or Enfamil? There have apparently been quite a few incidents with the Enfamil formulas lately that have caused issues in babies, caused vomiting, constant crying, stomach pains, excessive diarrhea, death, meningitis of the brain and spinal cord, etc.
