Baby Multivitamin? EDIT

My 7 month old’s pediatrician said to start her on a baby multivitamin with iron while she’s over 6 months but not yet getting a lot of solid foods? I can’t find much, none in stores and only a couple on Amazon (I’d rather not order something like that online). What are you all doing for this? (I know I can call but it’s hard to get through.)

EDIT: Baby is EBF, taking vitamin D, and not anemic as far as we know (though Momma is). Doc didn’t say anything about anemia.
