how much for an 8mo

[NocturnalNonsense]

I'm bf my 8 month old ds but he hardly feeds at all during the day, feeding all night insted! he has one bottle at about 10pm and is generally pretty good with solids. I'm wondering how often other 8mo feed and for bottle fed babies how much they take each feed/in total?
We need to change our routine but I don;t know what to. Have been largely demand feeding dut demand is all between 1-5 and exhausting me.

at 8 months my ds cut down from 5 bottles to 4 with them being around 7oz each - so it went from approx 30-35oz to 25-28oz (the 5th bottle was in the night and he gave it up by himself at 8 months). He also had 3 solid meals.

sorry, timing of milk/solids were:

7am - milk
8am - breakfast
11am - milk
12pm - lunch
3pm - milk
5pm - solids
7.15pm - milk

I have a 7 and a half month DS and our routine is as follows:

7am ish - 7oz bottle
8am - breakfast
11.30-12.00 - lunch
1.00 - watered down 3 oz milk before nap
2.30-3.00pm - 6 oz bottle
5pm - tea
6.45pm - 7 oz bottle
10pm - 5oz dream feed bottle (but we are busy trying to cut this now)
