Allergy to yogurt

I'm a mom and a grandmom. My granddaughter may have an allergy to
yogurt and I'm wondering if any of you can shed some light on what may
be going on. The yogurt was mixed with fruit which complicates the
issue. Not sure which fruit. Both times, a rash appeared and in some
places it was just rashy and in other places it looked like hives. It
was dark red and was everywhere. It didn't seem to bother the baby at
all.

Is yogurt an allergic food?

Should babies of 9 months eat milk product? When my kids where infants,
we were told to wait until 1 year.

is she on formula or breast fed? if formula, is it milk based
or soy based? if breast fed, does she react when her mom eats
dairy/drinks milk? the point here is that she most likely is
being exposed to milk proteins in other forms.
yogurt is acidic. it can cause a rash anywhere it touches
skin if the baby has sensitive skin, but that doesn't mean
there's an allergy.
you could simply discontinue yogurt until the baby is older,
or you could try giving the baby plain, unflavored yogurt &
see if that causes a problem. there are several fruits used in
yogurt that can be allergenic: strawberries, blueberries,
peaches, mango, raspberry, banana... you could test her with
the fruits individually too (but it's really better to avoid
berries of any kind until after a year old because they are
very likely culprits in allergies).

My daughter (13 months) breaks out when she gets yogurt on her skin, but not
with other milk products. She also gets a similar rash with a few acidic
fruits, so I think the culprit is a reaction to things which are acidic as
opposed to an allergy, exactly. She also hyperreacts to anything which
irritates her skin, (a mosquito bite looks absolutely hideous-red, welted,
and covers half her leg easily) so it looks much worse than it is, and
according to her pediatrician, that sort of hyperreaction isn't uncommon and
isn't a true allergy, so I think the reaction to slightly acidic foods is
more of the same.
