In the early days mothers usually relatively overproduce.....and babies are small (on their lplates) They are often satisfied with just one side. But generally, over the fist few weeks after birth babies will come to want both sides at each feed. They get bigger and stronger and can guzzle down a breast in no time.
Babies have a way of keeping you on your toes - just when you think you *get it* they move on to a new stage. Keep up the good work
