Pumping questions

Hannah

So I very recently started pumping 1-2 times a day after she eats for like 10 min tops..that is what the lactation consultant told me to do to start building a stash and giving her a bottle a day to get used to it. I only get like 1.5-2 oz out of the one boob bc the other is pretty empty from her just eating. Is that normal for this point in time? She is 4 weeks old. Also she got her first bottle last night and did very good she actually guzzled the 2 oz down in like 5 min or less. I was worried she was going to spit it all back up. She was still hungry after that so I fed her from the boob. I need to go feed and weigh her to see what is filling her up, but I just wanted to know if these things are normal.
