Thank you both so much!
Things do seem to change on a nightly basis, but last night for example he ate at 10:30pm and then at 4:30am (I call this a good night), then at 7:00am not hungry... But the night before it was eating at 10:00pm, 12:30am and then still not hungry at 7:00am.
Thanks Liz for letting me know that I am not the only one!!! I just assumed all babies "should" be hungry for first feed!
