Is a little worth it?

Hi all!

My baby girl is about to be 6 months and I had planned to switch to full formula then. I have almost always had to supplement with formula due to a tongue tie we found late. Because of this I also have to pump after she feeds each time to keep my supply up. She gets 1-1.5 bottles of formula a day and the rest is breastmilk.

I have been counting the days to stop because while I find breastfeeding rewarding, I HATE pumping. Baby is healthy and reacts well to formula and has never even had a sniffle.

Now with Covid 19 I feel so guilty about stopping when I could potentially provide antibodies to her. I feel able to keep nursing and pumping a few times a day, but so you think a little breastmilk a day (say around 8 ounces for an example) would provide a little boost to her immune system or it's not worth it ?
