Hi A.,
No milk until she's one-year old!!! You do not want to give her any foods that kids are most likely to have allergies to until at least 12 mos, longer for any food that you or her father are allergic to. The earlier you introduce a potential allergan, the more likely she is to develop an allergy to it. According to Lucile Packard Children's Hospital at Stanford:
Approximately 90 percent of all food allergies in children are caused by the following six foods:
milk
eggs
wheat
soy
tree nuts
peanuts
Cow's milk is the food with the highest likelihood for allergy (still only 5%-6% of kids under 3, but why increase the chances your baby will be one of them). Until your daughter is one, continue giving her either breastmilk or formula, whichever you have been using or wish to use. As others have said, introduce one food at a time. Here is more good advice I'm copying from a website 'cause I'm too lazy to type it all up, but it's the same advice we got from our pediatrician, except that I think we introduced eggs earlier than two years, though certainly after one year -- maybe 18 months:
It is best to start with rice and oat cereals and introduce wheat cereals later. Next you can introduce vegetables, but avoid legumes (foods in the bean and pea family) at first, and then non-citrus fruits and fruit juices. Meat and protein foods can be added once your child is 8-9 months old.
Foods to avoid until your infant is at least a year old include cow's milk and other dairy products, citrus fruits and juices, and wheat. Also, avoid giving eggs until age two, and peanuts (as smooth peanut butter) and shellfish until your child is at least three years old. Whole peanuts and tree nuts should be avoided until your child is four because of the choke hazard.
When you do introduce new foods, do so slowly and only give one new food every four to five days. This way, if your child does have a reaction or allergy, then you will know which food caused it and you will be able to avoid giving it again.
