So my son is a little over 2 weeks and I feel like he takes 3 to 4oz every 3 or so hours. I usually make 2oz and then hes awake within a half hour wanting more. Is this normal? Lol I dont remember with my first son. Is he just outgrowing the 2oz serving? I'm doing breastmilk through bottle and also formula. He usually gets more formula, my supply sucks :( hes not throwing it up, maybe a little spit up randomly because he has reflux but he doesnt seen over fed...
