DS has been exclusively breast-fed. I have been delighted about this. I'm 45 and I struggled with DD four years ago. She was exclusively bottle-fed from four months. I had been hoping to keep Bf-ing him until he was 2, in line with WHO guidelines. However, while he feeds in a serious and concentrated way first thing in the morning, the picture is quite different later in the day. I feed him when he gets back from nursery (about 4pm, and more like 2.30 on non-nursery days) and again at bedtime. In the last couple of weeks, these feeds have become more and more desultory. He bites my nipples, giggles a lot and loses interest within half a minute on either breast. Is there anything I can do to make him more likely to concentrate? If not, should I just drop these two feeds? If I do, will one feed a day be enough to maintain my supply?
