I have dealt with a milk allergy before. Since you haven't met with the allergist yet you won't know for sure the severity. I have had one that was lactose intolerant so used the lacteeze milk (back then we had to use drops in regular milk and then it sat overnight to break down the sugars - mom did and brought it to me the next day - we are talking 20 years ago before cartons of lacteeze). This same child was ok if the milk was cooked such as in rice pudding or baking. She outgrew the allergy by the age of 3. Another child was ok on limited milk but was given the medication orally on a daily basis. So I didn't have to change my foods much but still limited him as in no milk for drinking, limited cheese, but it was ok for anything cooked or baked. The last child I had was allergic to the protein itself so no amount of milk was ok including casein, whey, etc so it was a lot of label reading. Once you figure out which brands of foods work you just stick with those. But you have to read them all such as some chicken nuggets are dipped in milk before being breaded, add water to scrambled eggs instead of milk, that sort of thing.

Most daycare providers are ok with an allergy depending on the reaction of the child. For instance I do not take any child that has an anaphalactic type allergy because I am only one adult. I can not give the sick child my total attention while still keeping an eye on the safety of the other 4 kids in care. A child with a severe allergy is better in a centre where there are more adults and a dedicated cook that deals with the various allergies on a daily basis. An example for me is a peanut allergy. While I rarely serve it to the daycare my own family uses it so we are not a nut free home.

You will need to provide your child's special milk and it is always appreciated that you share any brand names or items that you find are good ie you are spending the time at the grocery store doing the label reading and I just have to go in with the list of things to buy. If the product/brand is much more expensive than the other ones the provider might ask if you would mind buying one to leave at daycare again ex. your child would get some of their special chicken nuggets when the others have the daycare brand.

What your child has been using for formula will go a long way to knowing the type of allergy. A child with a protein allergy can not eat any of the canned formulas including most soy, or other alternate brands since most contain at least some milk products such as whey.

Instead of the parent providing the meals I have actually found it is better for me to do the providing but I did have to raise the rate by a couple dollars a day for one family because of the more expensive brands that were needed for their child and just for the extra work needed in specially making certain items so that is also one thing to consider in terms of budgeting. It might be easier for you to pay the extra per day rather than to have to bring the extra items. Although as far as the special milk for drinking that would always be your responsibility I would think since it isn't always available at the corner store and can get very expensive.
