Baby’s milk intake

When did your baby start eating cereal and baby food and did your baby not drink as much breast milk because they were eating real foods?

I pump about 40oz a day and baby drinks 30-35oz a day. So I freeze 5-10oz.

When baby is 4 months I was told I could give her cereal from a spoon. I’m wonder is baby will still be drinking 30ozs a day or if I can cut my middle of the night pump since she won’t be drinking as much milk. Also when your baby is 8 months+ and eating more real food how much milk are they drinking a day. Trying to figure out when I can stop pumping all together. And trying to give her milk till she’s at least 1 but would go past if I have the milk.
