don't blame yourself, not all mothers are the same and neither are babies, you breastfed them as much as you could, that's fine and you don't have to feel bad about thinking about more time. I only have one son and I breastfed him for 11 months. Those were very difficult months for me because I weighed around 40 kilos, can you believe? I could not imagine having tried it with 5 babies, you are a super mom 🥰
