Dropping milk

[1Pinkfluffyelephant]

Since introducing (late) breakfast as well as dinner to DS this week, he has dropped his milk intake from around 36oz to 24oz.
Is this a big drop so quickly? If he looses weight will I notice fairly quickly (he isn’t due to be weighed for a month now).
Just for a rough guide he has:
4am - 5oz
8am - 5oz
Nap
12pm - half a weetabix or ready brek
Nap
3pm - 4oz
5pm - dinner
6.30pm - 8oz
He was previously having x4 7oz bottles and one 8oz at bed.

Did you take a bottle out or did he drop it himself?
What age is he?

He is 7.5 months. It’s since having the breakfast he isn’t wanting his lunch time bottle like he is full. I offer it but he isn’t interested.

He just seems less fussed about his bottles in general as he is taking less at each feed but still being offered his usual 7oz
