My DTs are 13 months, I have an elder DS of 3. After stopping BF DTs at 9 months, AF came back, but has been irregular - sometimes shorter, sometimes longer, sometimes like now, absent. Am 40 and v anxious am reaching perimenopause. I am also getting hot, particularly in the middle of the night. I got pregnant both times right away so assumed I had a good few years in me yet. Wondered hopefully whether anyone else after multiples took ages to get back to 'normal'..
