BF and food/water intake

It depends what you mean by "should be" if you're eating a varied healthy diet and drinking a good amout of water each day then it's unlikely your supply will be effected.

With my first I was hungry all the time and was constantly eating. Never lost baby weight because of it.

This time round I'm less hungry and I only eat when I'm hungry. That could be 1-3 meals a day. However, I'm always thirsty so I'm drinking an average of 3-4 litres of water a day and some days I'm still thirsty! Xx

I am eating how I did pre-pregnancy only I'm now eating breakfast, I am drinking more water but otherwise my diet is the same as before pregnancy, I am EBF and pumping / collecting 300ml a day for a freezer stash and for a small bottle a day for babies vit d to be mixed into. X
