Last bottle of breast milk 😭😭😭

I just gave my little boy his last bottle of breast milk 😭😭😭

Back story; I was exclusively pumping and my supply started decreasing, I’ve tried everything to increase it but it didn’t work 😟 It got to the point where I haven’t pumped more than 40ml from both breasts together and it was basically just water so I stopped torturing myself and stopped pumping. I had a little stash in the freezer so I was combing formula and breast milk for few days and now he will be on formula only 😭😭😭
