P.M.
Congrats on nursing past 1 year!!
Sounds like your daughter still wants to nurse. Why is it such a hardship for you to continue nursing your daughter? At this age, her nursing is probably at MAYBE 10 minutes per session - if that long. How can that ruin your day even if it's 5-6 times a day? Maybe you need to ask yourself why you are so frustrated with breastfeeding and try to work towards solving that rather than forcing your young barely into toddlerhood toddler to stop what she needs.
Nursing at this age soothes so many problems, insecurities, hurts and allows her to recharge with Mommy. Nursing makes them feel safe, loved, comforted and gives them a steady access to superior nutrition and antibodies - no matter at what age.
I should also remind you - each child is different just like each pregnancy is different.
