This may be a really stupid question but I gave birth to my baby boy two days ago and for the first 24 hours he wouldn't feed much. That's all changed now! He's just fed for an hour on one boob and I'm not sure if I should be moving him into the other boob in case one runs out? Can you run out? I've alternated which each feed but this is the longest he's fed so far and I don't know how to tell if I'm still making enough milk for him. Tia
