I’ve pumped for 18m (to slim down and maintain my weight), but still I get comments saying that bm is useless after 4m and baby should eat solids instead. Unless they are the ones producing the milk, waking up at odd timings to pump on your behalf (not donor milk), who are they to comment right? Be harsh if you need to, ask them to mind their own business. Regardless whether you pump or don’t pump, there will always be naysayers. Decide what is best for your own sanity and wellbeing. This is your body, your choice, nobody has the rights to put you down. Bm or formula, end of the day, everybody eats solids and fed is best.
