Hi. Your routine looks fine
Most people offer solids roughly an hour after a milk feed which is what you are doing, looks like 1.5hrs, that's fine if it's working for you and LO.
Milk is still the primary food source until much closer to 12 months so I would just continue as you are. It becomes clear when to drop a milk feed later on when LO stops taking a proper feed at one or more milk feeds, maybe around 8 or 9 months but it varies from LO to LO, the point though is that the switch of 1 milk feed to a solids snack with a drink of water would be led by your LO rather than led by you. When the time comes you would switch either the mid morning or mid afternoon milk feed to a solids snack with a cup of water, leaving 3 milk feeds in the day.
I've never heard that most babies take too much milk and that's not the trend I've see on BW either so I would probably disregard that, milk is still the most important food source for your baby.
Babies are usually very good at self regulating so will show signs of being full when taking solids, turning away, clamping mouth shut, or if you are offering finger foods just not taking them or dropping them to the floor. You can follow your LO's signs to know if he wants more solids or has had enough. The only time you might need to guide the portion would be if the milk intake dropped too much too soon.
There are not many foods you need to avoid but here are some guides
Foods To AvoidWRT trying for #2 I would suggest a thread on the BF board. I have no experience of this but lots of mummies have conceived whilst still breast feeding and I'm sure you would get some great advice and support there.
hope this helps, do shout out if you have more questions
