Ds1 has suddenly gone from a good eater, 6-7 ounces aevery 3hours ish through the day then 1 dream feed at night, to 3 ounces every 4 hours ish if we're lucky and 2 feeds at night. He's not sleeping so well either but otherwise seems happy and contented full of smiles and giggles. Should I worry that he's not getting enough milk or just ride with it for now?
