Formula guilt

I know that fed is best and I keep telling this to myself everyday but this stupid mom guilt is eating me up. I started supplementing this past week cause my Lactation consultant thinks our LO has tongue tie that makes him fussy and not finish up the breast. I started pumping like crazy which I’m not the fan of and I’m not making a ton of it through it ( only 2-3 oz per session ). The first couple weeks of BF I really wanted to quit and start formula but now after 3 months of EBF I can’t imagine stopping it and I hope if it’s truly a some sort of tie that can be fixed we can go back to BF. But I hate feeling guilty for giving my baby formula. I’m a formula baby myself, so as my mom. Only my MIL was super pressing me into breastfeeding my little one until 6 months because she has done it. Ugh sorry..too much ranting over here. All that matters is my baby finally started gaining weight 🙏 and I still provide at least 50% of breast milk for him to eat during the day so he can get all the needed nutrients.
