My son is just a little over 2 weeks and am wondering how long should he be allowed to sleep between feedings? He's been waking up about every 3 hours for feedings but today he's slept now for 5 hours and am wondering if I should've woken him up. I was soooo tired and just slept through the 3 hour mark. I was also worried about decreasing my milk supply. Pls advise.
