I fed on demand for the first 6 weeks, but "on demand" was more like every 1.5-2 hrs. The first four days I fed off both sides, but after my milk came in well, I switched to one side per feed. I never let him go more than 3 hrs between feeds during the day, usually every 2. Supply is SO important during those first 6 weeks, if you don't get it established well, you might still do ok, but you will probably notice low supply issues later. (Around 4 months ironically!)
We started EASY right away, Max loved the routine. He ate, he slept. He knew what to expect, that when he woke up, he got to eat. Start as you mean to go on! (And enjoy every tiny cuddle and chunky wrist!)
