Question about introducing new foods

DD is 7 months and has been trying all sorts of different stage 2 foods. I always introduce a new one, and wait three days (to see if she has an allergic reaction) before starting something new. I just tried Yo Baby yogurt for the first time (the 3 in 1 - pears and string beans, both of which she's had before) the other day and she's been fine (she's on soy formula but is doing well so far with the milk in the yogurt). I want to try a new flavor yo baby yogurt tomorrow (peach) and she's already had peaches before. Is it okay to introduce a new vegetable/fruit at another feeding tomorrow since I'm assuming she's okay with the yogurt (and she's fine with peaches)?

TIA

Re: Question about introducing new foods

once ds was introduced to something my ped told me the allergy was ruled out... so even if i gave him the breakfast jars they contained egg yolks... as a result i was able to just give him whole eggs and skip just the yolk... with yogurt i would rotate flavors since he had already had the fruits
