Mom guilt 😔

So at 2 weeks I had to switch my son to formula because he has a dairy sensitivity. Now his doctor told me I could cut out dairy and soy and continue to breastfeed. I also probably could’ve just cut out dairy or at least minimized it a lot. However I didn’t and I just switched to formula instead because I knew it would stress me out having to watch what i ate but now I’m having mom guilt he’s 7 weeks now and I just feel like a bad mom because I chose to give him formula instead of going dairy free and breastfeeding him. 😩😩
