Reintroducing dairy at 6 months

I've been dairy free since about 5 weeks because my LO had a suspected cows milk protein allergy. I say suspected because she was never tested, but when I cut dairy out she got much better within a few days and has been fine since. Her pediatrician said I could try to reintroduce dairy to my diet around 6 months because some babies outgrow it by then.

Well now she's almost 6 months, and I'm thinking about trying dairy again...please share your experiences if you went through this as well. How did you go about it and did it work for you?

We're also planning to start solids when she hits 6 months, but I'm worried doing both at the same time may be a bad idea, so if you have a recommendation for dairy first or solids first and how it worked out for you I'd appreciate that as well.

I plan to ask for her pediatrician's recommendation as well, but want to hear from you all about your experiences.
