Not interested in milk

Anyone else’s LO not interested in drinking their milk anymore? I thought it was just a phase Bc of teething but it’s been like this for a while now. He will only drink about 5 oz once a day and then maybe something around 6 oz spread out the rest of the day. He has finger foods 2-3 times a day. I figure he prob just isn’t interested in milk since he gets solids. But I’m concerned Bc he’s not getting anything near what I hear others are taking. He gets breast milk in a bottle. I’m not bf anymore and what he gets now is from our freeze stash. And he’s on the fastest flow nipple.
