If your LO had a sensitivity/intolerance to dairy as an infant and you had to cut it from your diet, did he/she grow out of it? If so, when, and how did you trial it? Did anyone's LO go on to have a true dairy allergy?

DD is only 11.5 weeks with a suspected sensitivity, so I don't expect to add dairy back in to my diet any time soon, but I'm just curious!
