So this whole sleep regression is really messing w my system

Typically I can pump about 30 min after my first morning feed and get about 5 oz. This has allowed me to keep up w daycare bottles as my afternoon pump doesn't. It also gives me a bit of a freezer stash. LO had been usually sleeping through the night for about a month. Now we are having multiple wakeups and he is eating at least 1x around 4 am. He wakes again at 7. Now when I pump after it's 2-3 oz. Today I am taking milk from the freezer for daycare bottles. Should I just ride this out and hope we regulate soon? Or should I be doing something to boost my supply. He has been going to bed a bit earlier and I am up later than him....perhaps I should pump before I go to bed? Or pump after his 4 am feed instead of 7 am? I know it wouldn't be the end of the world if I had to supplement a few oz, but I would really like to try to ride this out without doing that. Thoughts?
