Expectations vs real life

Denicza • First baby. What a blessing !
When I was pregnant I had this idea that everything would go my way,  I was excited to breast feed my baby and I was willing to go through the ouch my nipples hurt phase. Once I had the baby I had emgorged breasts, I produced a good 8 ounces of milk and it was amazing! Next day it was less, and less and less. I started supplementing. And I'm trying not to get depressed about it. I wanted this to be perfect, have all this extra milk supply, I tried lactation cookies that didn't work. It makes me feel like a failure as a mom and I'm trying not to think like that. Formula is not the end of the world. My son is eating and gaining weight and that's all that should matter.. At this point idk if I should keep trying to get that milk supply I'm looking for or just stick with formula. Is anyone going though the same !
