Continuing breastfeeding

Amy • Mommy to 2 boys and wife to an amazing man ❤ now pregnant with #3!!
My 16 month old son still wants to breastfeed even though I made the decision to quit 3 weeks ago. I really enjoy breastfeeding the first year but beyond that I just want my body back to myself! Is that wrong?? He still tries to get to my boobs occasionally so I can tell he wouldn't mind getting a snack every once in awhile. I just want some time off before I get pregnant again by the beginning of next year.
