Breastfeeding help


I have an almost 5 week old (how is that possible?!). I breastfeed mostly but supplement with formula as well. I am feeling like a bad mom for supplementing which I know isn’t true but I need some reassurance.

I also feel like a lazy mom because my husband takes one of the night feeds and I don’t get up to pump or anything. At night when she gets up she usually only drinks from one boob , should i be really waking her up to eat from the other? She is gaining weight well so no concerns there, more concerned that I’m screwing everything up.
