Weaning - which do you give first?

So my baby is 7months corrected 14weeks (23 week premie) and it is now week 5 of weaning. So far I have been giving 2 meals a day with milk after each meal and she’s been doing very well. We are now on 3 meals a day from today.

LO has never drank more than 550ml per day which is on a good day and I read its recommended 600ml. On a average day she has only 450ml and has never drank more than 3-4oz per feed. Has 5-6 feeds per day. Docs advised not to wake her at night for a feed no more.

Please could you advise what’s best? So far it’s been meal and then generally wait 45-60min and give her a milk feed before she naps.
