BLW questions replacing bottles for meals, transitioning to sippy cups, transitioning to whole milk and trying to break the habit of moving a bottle or something to drink to sleep

hi, so long story shirt with my first child by the time he was nine months I transitioned him to whole milk and by the time he was a year he no longer drink bottles. He was only drinking two open cups or some sippy cups, and he didn’t need a bottle or anything to drink at night to go to sleep anymore. I know it sounds like much but I want to try to achieve the same thing with my six month old so he already started eating meals. He’s not eating complete meals and I haven’t started replacing like bottles for meals yet because he’s showing interest for food yes but not to the point where I feel like he will be full so like does anyone have advice for that like do I just keep replacing a bottle for a meal until he’s eating three meals a day and start giving him regular meal through sippy cups so he can get used to it like what do I do to achieve the same timeline that I did for the first one because every baby is different but I kinda wanna keep it the same and this is unknown judgment post or zone. I don’t need Google doctors to tell me what’s wrong. I don’t need doctors to tell me what to do if you don’t agree with it just don’t comment but for the mothers who agree with it I would like your advice I’m Hispanic and this is how we do it in my household and we’ve all grown and raised just fine.
