Same with my baby and I realized she has been teething? In my experience I think it wouldn't be an issue with milk since he's eating three meals a day? Maybe introduce some snacks too, that's what mine does...and still nurses constantly on top of that lol
Teething! My baby only bites when teething.
For us biting means teething but my daughter also definitely doesn’t get full from breastmilk anymore. Around 12 months we really started prioritizing meals and then would nurse after (about an hour) if she needed a snack/comfort and now she’s only nursing upon wake up, to nap, and to sleep.
