Hungry, growing boy or something else??

Caitlin

So a little background.... I BF my daughter until she did self-led weaning at 9 months. She got bottles of breast milk occasionally, but not regularly until 9 months when she switched to bottles...

Now we have my son who is 3 weeks old... I had to supplement with a bottle after 2 days as my milk wasn't coming in fast enough and he was screaming all the time because he was hungry(something that didn't happen with my daughter). Now my milk is in and he nurses for a good amount of time, but is still seems hungry after BF and will eat an additional 1-2 ounces from a bottle. Does this seem normal? I didn't have any issues with my daughter being hungry after BF...
