Formula/solids intake

My baby is 8mo and has now moved onto 3 meals a day. Usually something like readbrek and some fruit puree for breakfast, half a pouch meal, a finger food like a veggie tot and some yoghurt for lunch and for dinner usually a veg pasta sauce with pasta stars, another finger food and the rest of the yoghurt. He doesn’t eat it all.

He still has 3x bottles in the day at 7oz and he is still waking in the night. I offer 6oz in the night in the hopes to gradually wean him off the night feed and move the calorie intake into the daytime. However with all this it works out he’s getting roughly 27oz. Sometimes it will be more depending on how the day has fallen.

When do they start dropping a bottle? What are the typical signs? Also he doesn’t always finish his bottle in the day but will drain his middle of the night bottle so he’s clearly still hungry. Any advice? I hateee weaning. There’s so much mental load to it lol
