My baby boy came at 34w on the dot. He is now exactly 1 month old he us taking anywhere from 30ml-140ml roughly however 60-80 is his most common amount he takes I've noticed he eats every 2.5-3 hrs very rarely every 4hrs like wtf usually he will go a few feeds consistently but then his pattern will fluctuate is this normal? If not how do I try & normalize his feeding?
