You have received awesome advice but wanted to reiterate. Your baby is spot on for a growth spurt and wonder week and I agree all the feeding is to boost supply...topping up only messes with the demand he is trying to make. His weight gain is excellent so I think your supply is awesome!!

A sling is so handy in the evening. Now the days are longer try taking him for a gentle stroll so you don't go insane from constant feeding.

You're doing perfectly!!!
