Dropped 12pm Bottle

I’m hoping some mamas have some insight and ideas before I see the doctor next week. My 9 month old (mixed fed) son has stopped wanting his bottled breastmilk during his noontime feeding. He’s been tasting solids for a while now but has recently wanted more and more during the day (I’m guessing growth spurt) and only wanting solids during that particular feeding. He still wakes in the middle of the night for a feeding (anywhere from 12am-2am; bedtime at 6:30pm). Anyone experience something similar before? I’m thinking I have to power through the night with him so he drops that feeding and takes the lunchtime feeding again. Then part of me thinks if he’s hungry at night I should feed him and if he’s not in the day I should be comfortable just giving him the solids for that one feeding. He takes the morning and afternoon feeds like a champ still. He just seems to not want the 12pm milk. Thoughts before we see doc for regular 9 month checkup next week?
