Just be aware that different products have different recommended quantities. Some are a total of 1L per day, some 1.5L per day. So make sure you are following the feeding guidelines for the product you are using

The danger with overfeeding at one feed is that the milk overflows the stomach that can deal with it (the abomasum), and then causes problems when it gets into another stomach (the rumen) where it cannot be digested.
So at any stage, each feed needs to be not larger than the capacity of the abomasum.
jaykay explained it all really well in
this post and I have paraphrased a bit of that here.
