Breastfeeding

Megan
I had my baby on Wednesday night (11:26)  on Thursday we had a hard time nursing and started supplementing because he wasn't latching  it started to get a little better by the time we came home on Friday.  That evening I started pumping because he wasn't getting anything. Saturday he would latch for 30 mins on (15 each) and be content for 2 hrs.   Yesterday(Sunday) he wanted to nurse every hour for 30 mins  and only had two wet diapers from 7am to 4am.  He nursed from 4-610 this morning and still wasn't satisfied. I ended up giving him 1.5 oz of formula and he slept 5 hrs and woke up soaking wet plus had some on his clothes and then had another wet diaper two hours later
 Is it possible that I'm not making enough milk to satisfy him & that's why he's constantly wanting to nurse or is this normal?
