I've just wrote a reply to a different op about much the same thing:

In early weaning (as in from about 6-9 months) solids want to be in addition to milk, not instead off.
Milk is the most calorie dense foodstuff baby can have, gram for gram. It is calories baby needs. Remember most early weaning foods are low calorie foods like fruit or veg. So you shouldn't be giving these at times baby could be having milk.
Given the increasing need for calories due to increasing motor skills around this age, it's not unusual that milk intake post-weaning is actually more than pre-weaning. It's a misconception to think solids will 'full up' baby - it's not a physically full tummy that baby needs, it's calories.
My 91st centile baby was on 2 hourly bottles pre-weaning. 7oz bottles at 7am 9am 11am 1pm 3pm 5pm and 7pm. Post weaning I jumped straight into 3 multi-course meals but kept the seven 7oz bottles a day.
It was literally like a return to the newborn days when baby spent almost all of her days either feeding or sleeping. Our routine at 6-7 months was:
7am milk
8am breakfast
9am milk
9-11am nap
11am milk
12pm dinner
1pm milk
1-3pm nap
3pm milk
5pm milk
6pm dinner
7.30pm milk
As weaning became more established, portion sizes increased and more food groups covered (in particular protein), then milk feeds were dropped. But this was more like 9 months.
For reference on portion sizes, each meal for baby would consist of:
- one 6 months jar of something savoury, spoon fed
- a plate full of whatever I was having, as I was having it. Given as finger food.
- one yoghurt, spoon fed
- sliced fruit as finger food
So each meal involved four courses. Two spoon fed so I knew the calories went in, two as proper food given the same as i serve to the rest of the family. Over time more of the proper food was needed so that purees were no longer needed.
