Can you offer me some advice please??

Hey mamas! This is a bit of a long and tricky one for me, my little girl turned 6 months on the 3rd. She has 8oz bottles 4x a day - so every 4 hours (she doesn’t wake for one at night) she has recently started to cry when it’s all gone, however, I don’t think this is down to hunger because if I leave her playing with the bottle or if she is distracted she doesn’t cry! She has also been getting weaned for a while tbh but she now has meals so, she has breakfast (7.30am with bottle) and also has dinner (6pm) I know she js missing a few oz going by the box, so really my question is, would you up to 9oz 4x per day instead of 8oz. She did move to 8oz early and she did with the 7oz too etc. she is a big baby, however not chunky and my concern is that if I up her oz she will end up being ‘over weight’ and I will be told to limit her food, surly she should be wanting less oz seen as she is eating solids? Feel like I’m in a catch 22 cos people will be so quick to say ‘mummy is starving you’ cos she cries after the bottle but genuinely I don’t think it’s hunger, I have tried her with a 9oz before and she still does it.
